Title says it all.
I was doing a tagging sweep and it occurred to me that quite a few times since I joined I've had to retag posts of male characters playing with obviously "male" dildos. I get that a featureless toy wouldn't really contribute to the sexuality tagging since I've met a few guys who like anal play but wouldn't go near another man in that way due to being straight. But what about dildo shaped like another males cock? I asked myself, didn't have an answer so I'm asking here.
The second quarter of the question is,
Should males and tentacles really get a male/male tag? Shouldn't the tentacles be considered ambiguous?
What about disembodied hands?
The hands one actually had me in trouble once because I kept trying to tag it as ambiguous... it was someone's hands! But couldn't assign a gender due to no body... see my dilemma?
