Since you guys are shifting this into the hook-up department, I'd like to add stuff: In regards to using both Tinder and OKC, this is my unscientific experience:
Ego aside, I ignore roughly 94% (shit out figure) of messages I receive.
Of those who are actually local and look real good:
3/4 will message me talking about my looks
1/4 will message me with a more "gentlemanly" tactic
3/4 will sever connection when they realize what is what
1/8 will ask questions about what my existence even means (basically, 1/8 are curious, but not THAT curious)
1/8 will say "I don't care, let's hook up"
I can't say if that last 1/8 are chasers (guys who actively try to date/hook up with trannies) or simply can't tame a raging hard on enough to care.
The guys who I start texting, sending pics to, go out with, all identify as straight, and none have ever been with a man.
Rarely, but often enough, I'll get the open-relationship couple who want to add some sriracha to their stir fry. I've never made a serious attempt to do that. My #1 reason is that usually the guy seems like a 5/10 beta in these open relationships... I haven't the foggiest clue why, but I have theories.
Finding a nice looking lesbian who is interested is as likely as Wizardhawk finding a girl (period) who is interested.
-big fat edit- I don't go out often enough to bars to gauge my luck there, sorry!
