helppp

the guy im dating has always said that he doesnt care about the sexual side of a relationship, but its pretty evident he does. I havent done anything with anyone before, and he knows this, but im scared to tell him that i just wanna wait for a bit? i mean not forever, just I want to be comfortable first. Hes a great guy really, im just worried he'll go and tell all his friends that im not willing to do stuff with him even though we really havent been together long
