Hi,
I'm a straight trans. Well for me it's BEAUTY, BEAUTY and BEAUTY! If your Beauty is FATAL and overwhelms the average bio woman, you are more likely to overturn all straights BUT a big BUT, they should NOT know at all you are trans. Or 'knowingly' STILL I would opt for PHYSICAL BEAUTY. A super model-looking face and PASSING face. But this too, the chance are minim as soon as they know you are trans.
To what I've learnt it's VERY difficult for a real 'strict straight' (who are most of the time the ones who look the most handsome, very manly and very attractive) continue accepting you once they know you are trans.
The straights who are likely to accept you are the what I call 'Moderate straights', I don't mean that they are ugly, fat etc as you say, but they generally appear 'normal' (neither superhandsome, nor super ugly but fairly good-looking)
And the '->-bleeped-<--->-bleeped-<-s' omg don't talk about them to me, I don't like them at all. In fact me too I get turn off as soon as I know a guy is ->-bleeped-<--->-bleeped-<- looking for ->-bleeped-<- with penis etc and reject them...just like a strict-straight guy turn me down for being trans. Generally you can grasp at a glance one is ->-bleeped-<--->-bleeped-<- by their face, their face look something between gay and straight and have a 'soft face vibe'. You don't feel that 100% 'virility' like the 'strict straights' ones. I can make VERY RARE EXCEPTION for a ->-bleeped-<--->-bleeped-<- ONLY if he looks super handsome(that too only for sex and not to love) and resembles a straight guy and he must behave with me like he's treating a woman and not a ->-bleeped-<- with penis cos am entirely passive but generally I turn them all down.
But SADLY, you can the most beautiful POST-OP TRANS IN THE WORLD but as soon as a REAL STRAIGHT MAN(STRICT STRAIGHTS) knows you are trans, they will turn you down by experience I've got, SO THE BEST AND ULTIMATE WAY IS JUST BE A VERY BEAUTIFUL PASSABLE BOMBSHELL AND MAINTAIN YOUR MOUTH SHUT, PERIOD!
