Scorpio pops to mind and no, I haven't. I rarely have sex as it is.

I've never heard of this before.

Googled and it sounds to me like it stems from seriously low self esteem issues ...so 2nd/8th house axis comes to mind.

So, it depends on what rules this axis in a chart i.e. all of them can do this!

But if I must give an oversimplified answer, then I would guess Taurus/Scorpio.

No

Not Scorpio .... well, not this one ....haha 

Is that when you SO cheats on you, then you go out and cheat on them and you let them know all about it to try to make them feel bad?

I don’t know but it sounds like an immature person.

Argh. 

I think my earlier comment was confusing.

All of them! Whatever signs that sit in a chart's 2nd/8th house.
