I don’t plan on ever breaking up with him lol. So the thing is, it’s my first relationship. Okay. We’ve had sex. I love it. I love the way the D feels okay lol. But I’ve always had a fantasy about going down on a woman. I’ve never done an with a woman or even had interest in women. I truly

Can’t see myself being like in love with a woman I just want to go down on one. I’m straight and I love lesbian porn. Last night I had a sex dream where I went down on a girl.

We’ve talked about having a 3 some before but we’ve never like actually actually thought about truly doing it. Just the idea of it. And I know you don’t know if you like something until you try it.
