Sex drive

Sex drive (also called libido) is your level of desire for sexual activity — how often you think about sex, how interested you are in it, and how much you want it. It varies hugely from person to person. Some people think about sex a lot. Others rarely do. Both are normal. Your sex drive can also change over time depending on hormones, stress, mood, health, and what's going on in your life.

• Sex drive is how much you want or think about sexual activity. Also called libido.
• There's a massive range of normal. High, low, somewhere in the middle — all fine.
• It's affected by hormones (especially testosterone), stress, sleep, mental health, medication, and the menstrual cycle.
• Sex drive often increases during puberty as hormone levels rise.
• Having a low sex drive doesn't mean something is wrong with you. Having a high one doesn't either.

What affects it

Sex drive isn't a fixed setting — it shifts. Lots of things influence it:

• Hormones — testosterone plays a big role in sex drive for everyone (not just people with a penis). It rises during puberty, which is part of why sexual thoughts and feelings become more noticeable. It also fluctuates across the menstrual cycle — many people notice higher sex drive around ovulation when oestrogen and testosterone peak.
• Stress and mental health — anxiety, depression, and stress can all reduce sex drive. If your brain is overwhelmed with other things, sexual desire often drops. This is normal and usually temporary.
• Sleep and tiredness — being exhausted kills libido. Your body prioritises rest over sex when it's running on empty.
• Medication — some medications affect sex drive, including certain antidepressants (SSRIs are known for this), hormonal contraception, and antihistamines. If you notice a change after starting medication, mention it to your GP.
• Relationship factors — feeling safe, attracted to, and connected with someone can increase desire. Feeling pressured, anxious, or unhappy in a relationship can decrease it.
• The menstrual cycle — sex drive often rises around ovulation (mid-cycle) and can dip in the days before or during a period, though this varies a lot.

During puberty

Puberty is when most people first become aware of sexual desire. Rising hormone levels — especially testosterone — trigger new feelings: attraction, arousal, curiosity about sex, and sometimes an overwhelming amount of thinking about it. This can feel exciting, confusing, or both.

Some people notice their sex drive early in puberty and strongly. Others develop it more gradually, or later. Some people go through puberty without developing much sexual desire at all — which might mean they're on the asexual spectrum, or it might just be their timeline. There's no schedule you're supposed to follow.

The comparison trap

It's easy to think everyone else is hornier than you, or that you're hornier than everyone else. Both assumptions are usually wrong. People talk up their sexual experiences and desires, or stay silent about them — either way, you're getting an inaccurate picture of what's "normal."

The truth is there's no normal amount of sex drive. Some people want sex daily. Some want it occasionally. Some don't want it at all. All of these are valid, and none of them say anything about your worth, your attractiveness, or your maturity.

Things people get wrong

"Boys always have a higher sex drive than girls." On average, testosterone levels are higher in people with testes, which can influence sex drive. But individual variation is enormous. Plenty of people with a vulva have a high sex drive, and plenty of people with a penis have a low one. It's not a gender divide.

"If you don't want sex, something is wrong with you." Low or absent sex drive can be completely normal — especially if you're stressed, tired, on certain medications, or just not that interested. It's only a problem if it's bothering you. Some people are asexual and rarely or never experience sexual desire — that's a valid orientation, not a disorder.

"Your sex drive should stay the same all the time." It fluctuates — day to day, week to week, year to year. That's just how bodies and brains work.

Things people ask about sex drive

Why do I think about sex all the time?

If you're going through puberty, rising hormones are a big factor. It's very common to feel like sex is on your mind constantly during this stage. It usually settles to a more manageable level as your body adjusts.

Why don't I think about sex much at all?

That's fine too. Not everyone experiences strong sexual desire, and it can develop at different ages. If it's not bothering you, there's nothing to fix. If it is bothering you, a GP can check whether something like stress, hormones, or medication might be a factor.

Can hormonal contraception affect my sex drive?

Yes, for some people. Hormonal methods (especially the combined pill) can reduce libido in some users because they affect hormone levels. If you notice a drop after starting contraception, talk to your clinic — switching to a different method might help.

Is it normal for my sex drive to change across my cycle?

Very. Many people with a menstrual cycle notice increased desire around ovulation and lower desire at other times. Hormonal shifts across the cycle are a real and documented influence on libido.

Sex drive means how much you want or think about sex. It's also called libido. Everyone's is different. Some people think about sex a lot. Others rarely do. Both are completely normal.

During puberty, most people start thinking about sex more because of rising hormones. This can feel intense — like sex is on your mind all the time. That usually settles down as your body adjusts.

Sex drive isn't fixed. It goes up and down depending on lots of things. Stress, tiredness, mood, and health all affect it. Some medicines can lower it too. For people who have periods, it often changes across the monthly cycle — higher around the middle, lower at other times.

There's no "right" amount of sex drive. Wanting sex a lot is fine. Not wanting it much is also fine. Some people don't feel sexual desire at all, and that's a normal variation too.

The idea that boys always want sex more than girls isn't true. It varies from person to person, not by gender.

If your sex drive is bothering you — either because it feels too high or too low — a doctor can help work out whether something like stress, hormones, or medicine might be playing a part.
