There *is* a rainbow at the end of this experience. Or at least, there can be.
I'm exclusively into guys, but after I started transitioning it took me four years to pluck up the courage to sleep with anyone because I felt somehow 'less than' them and was painfully self-conscious about the fact that I don't have the usual equipment. It was much easier trying to attract guys in female form, because I never had to explain away my equipment and let's face it, there's not exactly a shortage of guys who are willing to sleep with beautiful women.

But since transitioning? Not everyone is accepting, but to be honest I haven't had a lot of problems really. I tend to be wary of bi guys in particular because of their existing attraction to women: nothing makes me more uncomfortable than being treated like a woman and bi guys tend to know how to do that, so I'm cautious about approaching them. That being said, the most recent guy I slept with is bi and he was wonderful.
I always disclose before any clothes are removed. Most guys are already so interested in me by the time we get to that point that they're happy to continue, so a good time can be had by all. But if they don't react positively, that's fine: we've both dodged a bullet & we go our separate ways.
To help myself overcome my insecurities about my equipment, I try to turn my equipment into a USP. My masculinity is obvious when you meet me (nobody ever guesses I'm trans) and I prefer to bottom, so instead of focusing on what I'm lacking I actively promote the fact that I have a clean, self-lubricating fun zone that I'm happy to use. Most gay guys have only tried the salesman's entrance and as that requires a lot of maintenance, it can be great fun to try something different that doesn't smell bad & doesn't require loads of preparation.

But of course, it's entirely possible to bottom in all the ways that any other (cis) guy can do too.
TL;DR: most guys are horndogs, and if they're turned on enough by you when you're fully clothed, they're usually happy to go all the way & they don't really care what you're packing as long as they have a good time.
