I don’t quite know what the OP’s phrase “less sexual than men” means. I’ve got a pretty healthy sex drive, to the point where it sometimes exhausts my boyfriend’s daily capacity. But I’ll take these questions one at a time:
“A man’s willingness to frequently engage in sexual activities.”
Pretty important. If I don’t have any kind of sex for two days or more, I get a definite hankering. Current BF is happy to orally please me if his penis is too exhausted for actual intercourse.
“His desire to switch up sexual positions.”
Also very important. Missionary position every night would be incredibly boring, as would another, more exotic position if we never changed it up.
“His level of engagement while having sex.”
Definitely important. There can be times when we’re both distracted*, but if I know he’s really enjoying himself and connecting with me, it makes it that much better.
“His ability to go for extended periods of time.”
This is important to the overall satisfaction I get from sex. It depends on the timing, really. There’s a big difference in how long he can go; it depends on if he just ejaculated or if he last came 12 hours ago. I am occasionally disappointed if he finishes sooner than I’d like, but he does everything he can to make sure I’m satisfied, and I understand the limitations of self-control.
“His desire to have sex in different places.”
This is not all that important. Mostly we’ll have sex in the bedroom, but he’s up for sex in the bathroom, the living room, the kitchen. I’m always afraid of being caught if we’re not behind a locked door.
“His willingness to change up sex roles. (ie let the woman be the initiator, the aggressor, et al)”
Mildly important. I’m more often the initiator, and he’s not always willing if he’s distracted by something, but is usually up for it when I am. Beyond that, I’m pretty submissive in bed, so I’m happy to let him take the reins.
“His ability to have sex even if he “isn’t in the mood.””
Kind of important. We have had sex when he wasn’t 100% into it because I asked for it, but it’s much better when we both really want each other.
*I’ve given him a blowjob while he was playing Pokemon. The perils of having a gamer boyfriend. And I’m sorry to talk about him so much in this post, but hell, he’s my frame of reference.
