I think there are all kinds of hazards and opportunities if you leave the house. I have often been mistaken for someone attracted (you guessed it) to pussy. ME!
I would generally take being hit on as a compliment and an indication that people find you attractive --- as long as it is respectuful attention, otherwise ignore it. They are beautiful people too, probably a lot of them are cuter, more hung, richer and more accomplished and widely respected than you are as well.
My own experience is that all kinds of people can find one attractive. It's how they indicate it that makes the difference and possibly even more than that, their attitude. I personally find it most offensive to be hit on by drunk women (Call me a pervert!). Drunk guys are a close second though.
Yip, I've had it all, guys who want me to fuck their wives, intense guys at the gym, school friends (guys) hitting on me, bosses who want me to donate sperm, bosses who wanted me to fuck them. Gay guys and guys (who I think are basically straight) making moves as well and saying that they want to try it with a guy and I'm the one they want to do it with. And I mentioned the drunk girls....Then there are the mothers who want me to date their daughters, me! for gods sake!
How can I say "well maybe, but would they be able to appreciate this up their bottom?"
But I agree, some assumptions can be presented in an annoying way.
I always try not to be offended and say "thanks but no thanks" and maybe give them a compliment. It may be about their shoes, shirt (if it's Armani), or their eyes. But the energy of attraction is always a bit mysterious. I just want to feel that people are respectful and polite, and don't just see me a human dildo. Sexual attraction is an energy that we all need need to dance with rather than fight off or cling to.
