If men really think this way, then why do they get jealous when their girlfriend/wife/lover looks at another guy or worse...gasp!...sleeps with someone else?
Do we have a double standard here, guys?
Or is it simply that you want to do whatever you want to do with whomever you want to do it with--and not have anybody call you out about it?
Decide what you really want? No monogamy? Then don't call women sluts if they do the same thing.
