Some thoughts,
Like pp have said, it takes a while to actually know who someone is. Why would anyone invite a virtual stranger into their home (especially where there are dc, who are NOT in love with said person). Huge red flag when a male love bombs a woman's dc, huge.
Inviting an actual stranger into your bed!! How can you possibly know whether a stranger poses a threat to you, yet you get naked and vulnerable to them? This is not a judgement on those who want to sleep with complete strangers, if you're an adult you do want you want, but theres no way of knowing if you're isolating yourself with a rapist or worse, just from reading some of the threads of the consequences of this immediately opening to strange men is horrific. Do those who do this feel no fear, not even for a moment, wonder who this stranger is that they're naked with? Might they even just steal from you, or have a nasty unrevealed drug habit, sleep around, have aids, have other bodily fluid borne disease I mean, do these have no filter, just because someone has made themselves 'look good'?
Also, how long does is take to recover from a relationship? Having been through a divorce from a dh I loved wholly yet had to walk away from, I felt I would never find that with someone else and didn't want to look for anyway as I was devastated. How fair is it to approach others when you are emotionally unready? Its not fair to carry over previous unhealed relationship hurts to another person, is it?
The whirl of serial monogamy sounds like the perfect psychopath tbh.
Also, like there's some need to have to be with someone, anyone.
Pp have also said they have a high sex drive, is the implication that they are then allowed to use men to relieve themselves sexually? Not treat them as real people, not get to know who they really are, or care, just use another body for their own sexual relief.
That sounds crass at best.
Its like some have no souls or emotions.
I was interested in the pp who said they made a mistake in marrying someone that they were best friends with. Found that really odd, as my dh was my best friend, confidante, etc. Its been a requirement of my relationships, to have that trust, and connection, and know thats matched by my dp.
