I haven't had much problem with sex in previous relationships, as all of them were begun before I'd come out as trans. That being said, even then, I still hated not having a "real" penis (don't mean to disparage for anyone else's equipment, just that what I had, and what props I could use, just didn't feel real enough *for me*). There's this weird primal need to thrust and penetrate that is partially sated by using toys, yes, but it just isn't enough. And now that I'm single, I'm wondering "how do I find someone that's okay with the equipment I have, and still sees me as a guy". And even then, I worry that as supportive and cool with it as they possibly could be, what if it's still not enough for me, because I don't have a penis? I know that it shouldn't be the be all and end all (and it's not, really) but it is a huge part of sexual identity (not gender identity, but sexual identity).
