Until I read the part about his record with your G-spot and vaginal orgasms, I could not understand why you would possibly keep him.

He had relationships with two women telling each one that he loved her alone and that the other one was an obsessed psycho, on heroin or off heroin... - it seems enough to me for BOTH women to never want him in the future. No? I mean, this was cheap, lame, and dumb of him.

Also, to the extent that he is over 20 (since you are 46, and, since he made the other woman pregnant twice, I am making an assumption that he is over 20) and still does not know that one cannot will desire - that you have the desire or not and whether you have the desire is largely outside of your conscious control - he seems incurable as in "imbecility is incurable".

Then again, I am 42 and have not had vaginal orgasms and do not know if I have a G-spot, so to the extent that this guy was able to find your G-spot and discovered your ability to have vaginal orgasms, which is very rare in women, I can see why you might want to carry on with him. But for that reason alone!
