I'm a 15 year old virgin and at the beginning of the summer holidays a met this guy through a friend of mine. We got on really well and started dating about a week after we met. The only problem is now we've been going out for a few weeks he's started to change, he's not as sweet and caring anymore and has started to try to get me to do more sexual things with him. He says his last girlfriend and him had sex after two weeks and doesn't understand why I will only do basic things. Up until now I've found it so easy to tell people I don't want to do something, but I've told him I don't think we've been dating long enough to do anything serious and he won't listen. Please give me some advice, I'm worried soon I won't have the guts to stand up to him and I don't want to be rushed into anything I don't want to do.

I recently turned 24 and I have never been in a real relationship. I am in love with my best friend, with whom I have had a very interesting and painful 4 year friendship. He took my virginity at the age of 21, and he is one of 2.5 guys I have slept with; he is the only one I have hooked up with more than a couple times. He has cheated on two different girl friends with me, and he tells me he loves me but he has always been very clear that he will never be in a relationship with me. I have asked him a couple of times why. After a lot of beginning, he finally gave me list of everything that is physically and mentally wrong with me.
