I wouldn't give up on responses to your posts just yet. This is a forum, not a chatroom, so members come and go and will probably add their 2 cents to my 2 cents. Maybe you'll end up with a full buck's worth of advice and suggestions.
I check it from time to time to see the replies!
One thing I already see, regarding your last response, is the
contradicting information you're getting from your friend vs your wife, and some of the contradiction regarding your ability to hold your cum (as she posted here) vs her always asking you to "hurry up" as you mentioned. Do you think that maybe there might be some trust & communication issues buried somewhere? If there's an issue of trust now, think of how it will be when she starts banging some guys. And, it's likely she's going to become infatuated with some guy that bangs her
"really good". How do you plan to handle that inattention when it happens?
No trust issues that i know of. Never thought about how to deal with that issue, another reason we are asking for advice.
It's also interesting that you have a wife that seems to be on close talking terms, and in agreement, with your past GF. Love to know more about how
that developed. Its rare when you have a wife or current GF that's friends/talking with a guy's X'es. Also, what brought about your past girl friend becoming your X-girlfriend? Did the swinging have anything to do with that? Possibly your love making skills? Don't expect a woman to tell you that you're a shitty lover, USMC ... they rarely do that. They just quit fucking you. So, IF you suspect you may be lacking skills in the love-making department, its best you rectify that before you send her out to screw other men.
Just my suggestion ...
