help me please

I've been dating my bf for about 2 months and he already wants to have sex and it's like what do I do we've only been together for so long and he's already talking about sex I'm 14 btw and I really don't know if he just wants me for my body or he truly loves me cause this isn't the first time I've been dating a boy that just wanted me for sex I'm just trying to be aware cause I don't want to get hurt again
