you don't say how old you are, but maybe your just not ready to have sex. Maybe your not attracted to boys and its never going to feel good. Maybe your dry and it hurts and you need more foreplay?
Why not lay off the sex for a while and try getting yourself sexually aroused by playing with your clitoris. 98% of all females can't have an orgasm during penetration with a male. Its better to get yourself off than to have sex with some selfish boy anyways. If it feels good to have sex with yourself by masturbating then the problem is with the boys and not you, then you will know for sure.
If your attracted to other females then that will cause you not to injoy sex with a boy too. there's lots of time to figure all this out.. dont' rush it.
