[Sexual Communication] 30M I want To Propose Giving A Blowjob WITH my GF 26

For as long as I can remember I've been fixated by blowjobs, especially the woman's experience. I'm very much straight, I don't feel any attraction toward men but am VERY VERY curious about what it is like to give a blowjob. For the last few months, especially the last few weeks, it has become almost unberable. I NEED to experience this. It may be a one-time thing or something I end up enjoying in my sex life.

It all just fascinates me. I know how amazing it feels to have your cock sucked. My girlfriend is AMAZING with her mouth, by far the best I've ever had. She loves my come, facials, and practically begs to go down on me. I love her for it. I think this is partly why I'm so curious about being on the other side. Feeling the warmth, feeling it pulsate, tasting come, being somewhat submissive, and just making somebody feel amazing.

I'm almost at the point of finding somebody online and sucking them off no-strings-attached. But I can't cheat, it's really important to me.

I've joked (a little) about whether my GF would date somebody that was bisexual (I don't think I am, but curious), and she didn't seem repulsed and joked she'd then just have to watch out for guys too... just a way for me to test this a little.

We have talked about a threesome, probably with another guy, at some point in the future. My idea is that her and I find a guy and suck him off together. I would love for her to be there with me, show me, and make this an incredible experience for somebody. It also makes me feel much less worried about the safety aspect of sucking off a stranger.

So, ladies. What if your man confessed he wants to suck WITH you? Is there anything he could say to help convince you?
