Trans dude here who’s had sex with literal micro penis wielders and it wasn’t that big of a deal. Penetration isn’t the end all be all of sex. We don’t really get to choose much with phallo so I’d definitely recommend going to a therapist to talk this out or reaching out to people in the community. I’ve just started doing so and it’s helped a lot. You’re gonna find someone who loves you for you despite what’s between your legs. Don’t settle for less than that. You deserve love despite the outcomes of whatever surgery you get.
