How do you know when you're about to climax?

Tash

So I've been dating my boyfriend for almost a year and he hasn't made me cum yet, but during sex he asks if I feel like I'm about to but I just say no cause I don't know what it feels like, so can anyone actually tell me what it feels like when you're about to climax? Cause I asked my boyfriend and he says it feels like you need to pee but I don't know if that's the same with girls and he doesn't either cause we are each other's first.

TIA xx
