Yep, he wants to shag other woman and have you at home watching Emmerdale.
I remember reading a thread once (on another forum,) where a woman had been coerced into 'swinging' by her husband of 22 years. They went to a 'key party,' and her husband thought whichever man picked her would sit it out rather than shag her. However, the man was quite willing.
Her husband also didn't count on the fact that he would be swapping one 52 year old short, chubby, blonde woman, for another 52 year old short chubby blonde woman. For some reason, he was under the impression he would be shagging a 28 year old Holly Willoughby lookalike.
Much to his dismay, the man who ended up with his wife (the woman who posted on the forum) was 36, and was very good looking. Much better than the husband. He was also very good, with a lot of stamina, and satisfied her much more in half an hour than her husband had in 22 years.
The husband wasn't prepared for how jealous he was going to feel.
The marriage never made it to 23 years.
The man in the OP sounds like that.
Make sure if HE gets to fuck other women that YOU get to fuck other men @sasspot69
If you don't want to do this, then tell him to fuck right off and leave.
