I was thinking about this the other day--if my long-term GF was still into sex--she's not and hates it now, ever since menopause--I would likely do this very, very rarely.  

Well, let's think vice versa! Would it be fair if you had some physical issue and you could not perform in a nice sex for your GF/Wife then she was sleeping with handsome guys very often like you are doing now????
Don't bring excuse dude foe being a pervert!!!!!

First of all, that makes no sense and is needlessly argumentative, but I suppose that's the times we are in now.

i think you and your GF should seek counseling from a professional therapist.

That wouldn't help, she has a physical condition that now makes sex painful, but I love her so I stay. But I dont want to go the rest of my life sexless.

you limited your out of the house sex to one or two, maybe three providers. A friend (couple) of my wife and I had a similar situation. Trouble and disappointment for a couple of years. They finally gathered the nerve to actually discuss it with each other. Anyway they asked my wife for some recommendations and she was able to suggest a couple of not stupid nor indiscreet gals. He sees both of them two or three times a month with the wife's knowledge and permission, though she was very reluctant at first.  It gradually became a normal for them and "his" date nights have just become part of the activities of the month. I know him far better than her, but he says says everything is pretty calm and normal and the sex is seldom mentioned.  I doubt that would work for most. It took them a little over three years to reach the calm they now have.

Dude at least be honest with yourself. Simply you are a sex addicted pervert!!!! If you have problem with your wife/ girlfriend then you can have a fuck buddy or another girlfriend beside your marriage or relationship to get your sexual needs but look you have over 30 reviews means you have fucked over 30 girls!!!! and god knows how many girls you have fucked and didn't put any reviews!!!! so dear pervert dude just accept your pervert attitude and enjoy your abnormal sex life. Bringing excuse will not make a descent man or wash up your guilt. Just go and enjoy variety pussies as you do and you don't need to be  innocent like Jesus Christ!!!!

My hand is raised. My S.O. is very much into sex and I still play outside of the relationship. She's okay with it as long as I play safe and don't get too crazy. She says she has no interest in any outside fun but if she wanted to the same rules would apply to her. I've got 22 years on her, and 15 years with her so it's worked pretty well so far....

So if you have had sex with escorts as an alternative to zero sex with a woman to ou love, that makes you a pervert? No, it doesn't.  

You are either confused or hypocrite; I personally believe second option is applies more to you. Dude , love means unconditionally emotional commitment to your partner  if you don't have such a commitment it means there is no LOVE!!!
Plus let's say you still love your partner but you need sex , ok you can have a girlfriend to fulfill your sexual needs , you can have another sex partner or you can have one or two regulars escorts to fuck and get your sexual needs!!!! but when you have more than 30 reviews of different PROSTITUTES and countless fucking whores!!!! YES DUDE IT'S A SOLID PROOF YOU ARE A PURE PERVERT SEX ADDICTED HYPOCRITE!!!!!  

"Love means unconditionally emotional commitment to your partner".... I honestly do nor believe this is possible with humans.  To test it take your partner and your dog, put them in the trunk of your car then drive around on dusty gravel roads for a couple hours.  When you open the trunk the one that is happy to see you loves you unconditionally.

Dress them both in lingerie, put them on the bed, and asks yourself which one you would rather make love to.

My wife still loves sex after being married thirty five years except she loves it with other guys.  She does it with me to "keep me at home."  But she really performs when she's with a well hung black guy and gets extra wet when she is.  It's just that I'm safe and familiar and variety is the spice of life.  I love watching her play with others especially since she is still model material and they love her sexy body.  She knows in her heart I play with others but we never discuss my situation only hers.  It works well for us, we're happily, loving married but need variety.

It sounds like you both have the makings to be "swingers".  Have you tried it?
