How would you react to finding out you were making out with a transsexual?

Well, the pic in my thumbnail is a little out of date.  Like, I think it's from 2013 or so.  Here's a more recent one; it's less than a year old (it was taken while I was visiting Scottsdale).




As of now, I still want to explore sex, romance, dating and stuff like that, but I want to keep it casual.  I just ended an 8 year relationship so I'm in no hurry to get into another one.  I may just try to limit myself to more of the kink communities.  I'd feel more comfortable there since trans people seem to be more accepted.  

Here's another question, though: would it matter whether I'm post op or pre?  If you were making out with someone, you find out she's trans but she's post op: does it matter?  Or does it matter as much as it would if she was pre-op?
