Your comments don't add up to my experiences. I'll post my IRL experiences and my IN TEXT experiences.
IRL: This often occurs to me after I've ALREADY BEEN GRINDING WITH A GIRL AND HAVE A BONER! My reaction to her gay comment is usually either 1) Why would I have a boner for you if I'm gay, or 2) Well then, I'll have to prove how straight I am to you tonight.
Like I said, IRL it's less likely to mean disinterest, perhaps the 2nd comment is what they're sometimes hoping for, as it's lead to hooking up once. But I think it must mean disinterest sometimes since I've been turned down on using 2 before.
IN TEXT: Seems more likely to mean disinterest. I'll post a conversations I had recently.
(This was on Blendr, the girl's pic only showed her body in a hand stand, but no face. Her body was HB9.)
(My profile pic shows face and body. I'm somewhere between an HB9 and HB10. I'm a semi-celebrity model, fyi.)
ME: You're cute! We should do hand stands together!
HER: Lol thank you!
ME: U do gymnastics???
HER: Growing up
ME: Woot! Gymnast girls are the hottest!
I train it everyday!
HER: Nice
I just did it as a hobby
May I see a pic
ME: But if I send, u gotta too!
(I already had a profile pic, but sent her another.)
ME: There! Youre turn.
HER: R u gay
ME: Hey, no avoiding the subject. U owe me a pic, fair's fair!
Her: I don't think ur straight
Bye
ME: Hmmm, y would i chat with u and ask for a pic if i was gay?
Oh i get it, youre lesbian and just masking the problem on me. Jerk.
SIMILAR CONVOS HAVE HAPPENED BEFORE, THAT WAS THE MOST BRUTAL THOUGH. Could it be some girls think I'm too good looking for them (this girl might have had an ugly face), or could it be I might really look faggotish lol and some girls don't like that (I'm actually very masculine and straight looking, but have feminine mannerisms, for example, I had a lollipop in my mouth in the pic I sent her haha).
