I agree with you wholeheartedly barmaid.
I'm a big believer in what's sauce for the goose is sauce for the gander - or whatever the expression is. If you can't take it, you shouldn't give it - that sort of thing.
Sqad - not saying at all that swinging, 3-somes, swapping etc etc are perverted. Not calling you peverted. Just saying that surely not all men have sex on the brain and are 'up for anything' all of the time, any time, with anyone.
If someone is happy to do something without being co-erced, pressured, blackmailed, bribed - whatever, that no that is not peversion.
