The answer is that they DON'T have good sex.  You only know the lies he feeds you.  Unless you're hidden away in that bedroom and watching, then you don't know. 

How funny - mine used to tan too.  But NAKED.  He didn't like tan lines either.  He had to go to a foreign country on a work trip and he forgot to delete selfies he took of himself in the mirror wearing a super short, tight swimsuit.  I'd call them women's hotpants, for lack of a better term.  He's skinny too, but the damn suit was so tight that it gave him a muffin top.  Funniest pic I've seen in long time. 

Linda, when I read the part about going to the men's underwear section in the department stores, it certainly brought back memories. That's where my XH would go every time we went in a store. He also bought A LOT of underwear. He would also make derogatory comments about gays, though at other times he would say things in support of them.

Your ex's spiteful last text says it all.  The real purpose of his (rushed) marriage is to prove to the world - and most especially to you - that he is not gay.  How dare you divorce him and tell the world such a horrible lie??  He's not gay and his new wife-to-be is irrefutable proof of that!

It's all about spite - his text, his relationship and his marriage.  His top priority in life is to continue the lies.  He doesn't care what the consequences will be or who will suffer because of his selfishness.  When the novelty of his new marriage wears off, he will return to his old habits.  Be thankful that you are free of him and of living through that experience.

You are a loyal and loving woman.  Be confident in who you are and put yourself in situations to meet quality, single straight men.  Look ahead to a happy future, not backward at a man who would only be satisfied with you if you lived in his closet.
 

"Yes thank you.  He went out with his parents last night so they could meet her. I feel so sick."

How do you know this ?  Why do you know this?   Who cares

"Also shouldn't this woman be told"

I am the kindest person in the world and while I would feel sorry for the woman.. no I would not make any contact..  he has his life now..you have yours..   Its best you don't know anything about what he is doing.
NO CONTACT...zip...none.. he's the not worth any of  your thoughts.

Let us all have Tom remind us again;    https://www.youtube.com/watch?v=J3womK70af0

 

Can an alcoholic never have another drink? Yes - with constant effort.
Is he/she now no longer an alcoholic? No - one relapse and they might find themselves right back where they were before.

Sexuality goes deeper than a substance addiction so, in my humble opinion, it is very much more difficult to deny it. A few of us had spouses who desperately tried to suppress their sexuality but could not fight the tide indefinitely.

As for warning someone - that has come up here before. As much as it might seem noble to try to help someone else avoid our experience it's not likely to go well. If he is still in-denial you will sound like the jealous or "crazy" ex he had to get away from. If he's a skilled cover up artist he will spin it something like that and double up on his efforts to wine and dine this other person.

Just keep reminding yourself - not my monkey, not my circus.
The best revenge is living well.
