Honestly being non-op (for SRS, I've had chest surgery) hasn't really affected me negatively at all; even being a gay trans man who gets told a lot to "not feel bad when rejected because gay dudes are all about the penis", I've discovered that oftentimes people care less once they know you as a person than they think they would when confronted with your situation (not sure if that makes sense, but what I'm saying is I've dated several full-on gay guys in my time and a lot of them were surprisingly comfortable with me not having or wanting to have surgery down there. As for friends, I dunno what it would be like for girls (although my trans woman friends seem to have little issue communing with girls, both cis and trans?), but pretty much every cis guy that knows about my situation treats me no different than they would any other dude. And I'm finishing up high school still so if teenage straight guys can do it, anyone can! Haha. Seriously, don't worry too much, at the end of the day genitals are a pretty small part of the equation for people
