I usually get the same-six perk for several reasons.
1-gameplay effect. Most enemies out there are pure males, so it has a huge effect in the combat world.
2-Dialogue. Overall hilarious dialogue moments that can easily make your day a breeze.
3-Roleplay. I used to take it every time, no questions asked, now? It depends on my character. Brutus Kaiser flirts with males to make a humorous moment and get a laugh, even though he digs the chicks more. Whereas Carl, the lone ranger, is all about serious talk, and is straight, even then he doesn't like to speak much, so I don't take the perk.
