how come i cant climax?

Are you a girl or a boy?

I am a girl

Okay then, first you need to make sure you're comfortable with your surroundings. Sometimes trying to do it while other people are awake in the house and moving about can make you nervous if you are afraid of being caught. You might want to wait until nighttime or you're home alone, with the lights off if that makes you feel better.

Then you just need to relax, and not stress so much about actually having an orgasm. It is better just to explore and get into how it feels. Some girls likes stimulating their clitoris and can climax that way, others prefer penetration and might like it better actually fingering their vagina. The important thing to remember is that you're doing this because it feels good, don't keep stressing about the orgasm.

Just rub and massage different parts down there until out find out exactly what you like. It might also help to fantasize, whether about a specific person or specific thing that you think you would like to happen to you. While your sexual experience may be limited, you imagination is endless!

I am also a 17 year old girl with the same problem. But my main question is, what does a climax feel like? How am I supposed to know it's happened?

Try different positions to stimulate different areas or play with you clit while he is in you. Watch some porn it will give you new ideas relaxing a little helps too

I have done that but the problem is that my body basicly goes numb and I don't understand why... Why is that?
