I think sex with friends works well. If you have friends who are getting enough sex that they don’t mistake it for love.
As for people saying that sex without love is empty, I think they’re stuck in a black and white world. I’m closer to many of my friends (the ones I’m sexual with and the ones I’m not) than many people I know are to their spouses.
Also, sex isn’t better with someone you love, the cuddling and emotional security most people get exclusively with sex, are better with someone you love. I can state absolutely that sex is better with someone who is very sexual and willing to please. If you’re feeling lonely or unloved, you’ll get more of what you need from a snuggle with someone you love and depend on that sex with that person.
The people I know who would have a problem with casual sex are the ones who equate sex with intimacy (they are not the same, but are not exclusive either) in such a way that they can’t imagine one without the other. The other group who can’t handle casual sex are the near virgins who can’t get sex, to offer them sex is like offering a starving man food, and will come with a lot of baggage.
I’ve had good luck with sexual relations with both exes and friends who were on the rebound when I was. In both cases a relationship wasn’t what we were looking for, but we were compatible in other ways.
A pitfall though is only considering your ability to tell sex and love and relationship readiness apart. You also need to consider if your partner can. You aren’t responsible for someone else’s actions, but you’re going to feel the result of them.
Interesting. Melatonin found herself (?) less inclined to have casual affairs as she got older, I find the reverse. Maybe it’s because I was more emotionally needy when I was young. Certainly it’s because as I’ve gotten older I’ve been more able to determine what I feel and what I need than when I was young. (When I was young the answer to what I needed was ‘sex’, but what I felt was different every day of the week.)
Oh well, enough rambling.
P.S. I wish this editing window was larger, it’d help the continuity of long posts. Feels like using Magic Window on my Apple //+.
