Acting career kissing scenes: match the preference of your sim

My main actor sim is bi, so he doesn't mind kissing whoever his co-star happens to be. Most of the time it ends up being his best friend (male), who is currently married to his ex-fiancee, who also happens to be working on set as a producer. So the gender of his kissing partner is actually the least weird thing about this situation.
The most recent time he had to kiss a female co-star, it was his much older (immortal) distant cousin. So yeah. Maybe it would be better for him to stick to kissing guys.
