Let me just clear this up, because there seems to be some confusion. I'm not looking to "win," send a positive image, have game, win friends or influence people, hook up, date, fuck, be esteemed, not be laughed at, etc. I just want to know whether or not you would be offended, because I have no desire to cause anyone harm and consider offense the threshold of harm. And I think that I've successfully gleaned from the responses what is relevant to my question, i.e. that no one feels harmed by seeing me. I posted the pic to give a more concrete example, and still, no one seems to think that they would feel harmed.
But troubling to me is the assertion that I am being sexual with anyone. Are all of the girls at the gym whose vulvas are clearly visible (i.e. pretty much all of them) being sexual with me and every other man there? Of course not, and I don't really think that you want to be committed to a position which implies that they are. My penis is not erect. (I've read numerous posts on this site by women who do not think of flaccid penises as sexual objects.) It is not exposed. I don't leer or even make eye contact with anyone. My penis is just there like it always is. If someone wants to take that as sexual, then that is in fact that person's choice, not something forced upon them. Because, again, any man who claimed that a woman had initiated "being sexual" purely because of the way she chooses to dress would clearly be horribly mistaken. I really don't think that you want to say anything like that. I certainly don't.
I think you were missing the point of the responses. If your goal is to get strangers to look at your junk, you've lost. It reflects poorly on you, it suggests you have no real game, and it's off-putting to most women who would rather get to decide whether or not to be sexual with you. It's a bad move period.
