People who suck in bed. And not in a good way.
These are the folks who don’t want their partners to have the freedom of running away as fast as their lousy bed skills warrant. This is why they whine that nobody will buy their cow when the milk is free. To develop the ugly cow metaphor, the problem with the milk isn’t really that it’s free. The problem is that it’s of really low quality. The lousy lovers, however, want to get as many guarantees as possible that people will come back for their rancid milk and pay a good price for it before dispensing their worthless wares.
Of course, nobody wants to recognize that their hook-ups evaporate from their beds the first chance they get because sex with them is bad. It’s easier to blame the permissive society for that.
This is not a gender issue, in case anybody is confused about it. There is an equal number of men and women who complain about the fact that, nowadays, you can’t tie down a partner and obligate them to tolerate you in perpetuity just because you offered them some lousy sex at some point in time.
P.S. Note that the post title says “hates” and not “doesn’t feel like participating.” Please take a moment to consider the difference before leaving angry comments about there being nothing wrong with being in an exclusive committed relationship.
