Have topped a few times. Prefer to bottom. Typically it just stays at oral. Sexually, I enjoy giving pleasure. That's fun for me. But open to receiving as well. My wife knows I am bi, has seen me suck cock more than once.
And speaking of my partner/wife... My wife is ALWAYS present. She has played in threesomes when we've had other bi dudes over- not really her thing. She does like working me while I work you...so that may be a thing. She also sits back and appreciates observing my skill. If you are bi she can get off on you getting off as you watch us go at it and I make her cum. And at times I like juggling...so a tongue on your cock with a finger in her cunt may be just what I need. But regardless, she is always there. ;) I know that freaks a lot of you out. It's OK- man up. Get the fuck over it. Come over and play. Hell, everything in life should be tried at least once (or thrice!!!)!
