If your wacky son brings a boy home for dinner after play practice and you two are joking while you do the dishes and he says to you “Hey Ma, so… I’m not gay, but my boyfriend is!” and then you laugh and muss his hair and in the living room your husband shows your son’s boyfriend his model ships, then your son is probably gay, though he might be bisexual, so be careful about labeling.
Great article! Made me grin while making an important point.
