People can be assholes sometimes, but kuddos for sticking up for yourself. You did the right thing. It's one thing to be derogatory and vulgar, but to direct it towards you was wrong. Trust me some people never grow up and it's hard to trust people nowdays.

Hope things smooth out and they realize your over them and the incident..

sounds like your coworkers are scared little boys with small cocks. If i was in your position and some one had said I gave my neighbor a blowjob, i would have said "yeah, but he said you do it better". Let them treat you like a pariah, they are fag ass losers. I like sexual comedy as much as the next person, but there are lines you don't cross on the clock. so fuck 'em. wait...don't fuck 'em...fuck me instead HA! guess I am no better than the rest. I was just telling my friend the other day the the movie "Idiocracy" is starting to look like a documentary more and more every day
