The 10% damage bonus to all males sounds good since I'm guessing there are more male than female enmies. My question is will this open any forced gay dialog options? Also does Confirmed Bachelor stack with Lady Killer?

"Forced gay"? It does http://fallout.gamepedia.com/Confirmed_Bachelor, but all of these are optional.

Though if you ask me, choosing the perk just for the damage bonus when your character is not bisixual/gay is powergaming, not roleplaying.

Wow. Some of those dialog choices definitely seem gay but at least it's optional. I wasn't sure if other NPC's would assume your character was gay and start flirting with you. I remember a similar perk from Fallout 3 but it was only geared towards the opposite six.

They had a surprise gay ending in Dragon's Dogma when it first launched that could possibly make a certain male merchant as your love interest just because you interacted with him frequently for bartering and changing fighting styles regardless of you attaining a romantic status with a female. The thing is you would find out after the main quest that he was your lover and moved in your house complete with a cutscene that definitely caught me off guard.
