<human>: Provide a brief overview of the text.

I'm quite close with my little brother, he's my only sibling and our parents are very religious & strict so I'm the one he comes to about everything. A couple hours ago he came to me about issues he's having with his girlfriend, he told me that she wants to have sex and that he's nervous about it. They've only been dating for two months and he's only fourteen, so I don't want this happening. I told him that he doesn't have to do anything he doesn't feel ready for, but he thinks that if he doesn't do it then she'll break up with him. I don't know what to do and how to prevent him from having sex with her. I know some people might say it's his choice but I think he's far too young to lose his virginity and the thought of it just absolutely repulses me. Please help, I'm panicking.
