I think its just another form of human sexuality and its unfair to broad brush one group ...
there are lots of folks here that want to be dressed as a woman and have sex with men and/or women...is that creepy? i don't think so, and if you think these chasers are creepy then i wonder what people think of you?
men in general chase women...thats the way it goes...and yes, some of these guys are trans and can't admit it, some are gay and can't admit, so what??
I've met alot of guys and some creepers, most are not.
in fact, in my short time span living as a woman, the creepiest person i've met is a natal woman that stalks my friend and i at transevents...
