There's been a few posts and comments in the last 2 weeks with the claim that men as a whole strongly desire sexual variety, but this can only be satisfied by sleeping with new women. Supposedly, the lust directed at a man by the same woman again and again loses value and becomes boring, even with new sexual positions/activities. So, a new/strange woman who doesn't particularly care about your pleasure is still preferable to a familiar one who does.

Question for the dudes here, which would you prefer, and why?

Random Variety: To make this hypothetical fair to the men who have significant trouble getting dates, let's say you're guaranteed one new date every week. None of them want to be monogamous with you, but would be down to hookup with you by the end of the night. She doesn't really care if you are satisfied, and doesn't do anything to help or hinder your orgasm. It's purely ONS so you never see her again. You don't know her STD status or if she's actually on birth control, although she says she's probably clean.

OR

Stable Variety: You have a long-term girlfriend, no kids, and have been sexually exclusive for 4 years. She is on birth control, free of STDs, loves and desires you, and wants to have sex a few times a week. Although you obviously don't do anything involving threesomes or swinging, she's otherwise very sexually adventurous and enjoys trying out new positions, toys, lingerie, and other enhancements inside and outside the bedroom.
