Now there are some guys out there who won't cum for ages even if they want to do it quickly, they're trying to and it's the sexiest situation they've been in for a long time, but it's going to take time no matter what. For most guys though (at least around my age), that's not the case. We can't just let ourselves enjoy it as much as possible, because if we do it'll be over in no time. Instead, we have to learn self control, obviously, I'm sure most of us have been through this. We're not denying ourselves total pleasure as such, but putting it off and putting it off.
A woman on the other hand can go into a sexual situation looking to orgasm as quickly as possible without any worries (barring those EXTREME sensitivity cases). She doesn't have to put off her pleasure, there's worries of not satisfying her guy if she does ....
