Don't do it for meaningless, temporary kinship. Do it for money, money buys things, things form interests, interest make you interesting and therefore legit friends based on common interests and understanding.
If you don't lack the money, temporary kinship is the primary first step to get long term kinship.
(Also, sex is a legitimate interest. As long as you're on the lookout for people who actually wanna have fun instead of just getting an O and hitting the road, it's a really cool hobby. Or so I hear/dream. Not into any kink scene yet)
