Sure
Let me preface first by saying the best advise pops ever gave me was that life was too hard, too fast, too rough... too whatever... for anyone to rely on learning just from one's own mistakes. Better to learn too from the mistakes made by those around you. So...
When I was in my 20's I, like many of my butch friends, we were primarily interested in looks... gay ... bi... straight... didn't matter. If they were cute, if they were hot, we were game! I dated a few straight and bi women ... and it always turned into one mess or another. Within a few days... or a few weeks... I'd hear...
1. Oh no, I have a boyfriend!
2. You're sweet... but... umm.... I'm gonna go back to my boyfriend.
3. I just wanted to see what it was like.
4. It was a mistake... it was a sin!
After that happened to me.... maybe the second or third time... I swore ... more or less mockingly/jokingly.... off bi/straight women! I say mockingly/jokingly as if... I would really stay away from cute hot, girls of any preference! <-- Keep in mind I was in my 20's...young... dumb and full o'...
Anyway, so while I was in my "I'll never touch a straight / bi chic again!" funk... my butch friends weren't! They just continued on their not so merry way ... banging their heads against the same walls... over and over again. I watched and I learned. They all got the same responses I got along with lots of BS from the ex-husbands or ex-boyfriends who were typically lurking SOMEWHERE in the picture.
Guys are ...usually... fine if it's two femmes together but when it's his femme and a butch... nope, that's not okay!! My fellow butch friends would tell me how they'd get asked about packing.... asked what did they do to her... asked how big was their cock... if they were lucky... dumb ass questions were all they got. Some were not so lucky. I had two butch friends threatened and one beaten up by an ex-boyfriend. So, my half joking swear-off from bi's and straight women twenty years ago became permanent. No offense intended to anyone. You be you and I'll be me.
Simply put... I just find it unnecessary or worth the
potential hassle that can come from it. There are plenty of wonderful lesbian women out there who share my culture ... my history... my experiences...etc... etc... which puts us much closer being on the same page than does straight or bi women.
EDIT: p.s. I'm assuming by "straight" we mean first-timers?
