Good for you. I think straight guys in general do swing our way from time to time, there is an element of luck also.
But if you are femme you simply are more palatable as I said. I've been both masc and femme presenting, and there is no comparison. The number of guys I would get is 4-5 times more as femme twink. This is especially true when you go to countries or areas that are more rural or conservative.
The switch was fascinating and funny. It was literally a Clark Kent moment in my life, where I am the same person, face and body, but with a different aesthetic and the reactions were wide ranging.
Like I could hookup with a guy as femme and he'd be head over heels for in me in bed and then I see him a couple of months later with a moustache and he wouldn't even kiss me on the lips. The cognitive dissonance was absolutely hilarious sometimes.
This is anecdotal, but I've seen it with others, online and irl. Straight men love young bussy.
