An orgasm (coming or climaxing) happens when you are very aroused. Tension builds up in your body, the sexual pressure in your genitals is then released in a sudden pleasurable rush. Semen (white fluid) will come out of your penis. Women can release a clear fluid too.
Orgasms can happen during penetrative sex but they can also happen through foreplay. The important thing is not to put pressure on you or your partner either way, but to keep talking to each other.
If you want to reach orgasm and you feel you’re getting close, make it clear that you want your partner to keep touching you. Equally if for any reason you don’t want to orgasm, you can let your partner know how turned on you are but that you are ready to stop.
Don’t worry if you or your partner don’t have an orgasm straight away or even at all. It takes time to get to know what works for you and for your partner. Both men and women can enjoy foreplay without climaxing.
