Why is it ok for a 16 year old girl to date an old guy but not a 16 year old guy?

No one says anything about birds like blokedy smith dating bill wybloke. ditto for a young girl and her older lesbian partner ... no one would bat an eyelid.but it would be a scandal should a 16 year old schoolboy date a much older bloke. wonder why?
Answer
Its just the reputation old men get when they are dating a person (especially a boy) much younger than they are. it sort of makes it look like a pedophilic relationship in a way. its the same if a teenage girl gets a lot of action. they are veiwed as a s.l.u.t. its just the cultural view of things.
