here in switzerland is is normal to kiss a member of the opposite sex three times. left cheek, right cheek, left cheek... no big deal. you could also be shaking their hand while doing it, or putting your hand on their shoulder.

some men even do it. no, not only gay men, straight me, but it is more so among men and women...

there could be a few reasons. sometimes jelousy is from insecurity, and sometimes it is because they themselves are doing something wrong, so they assume you are too. guilty conscious
