Yes. I am current in a 3 year affair with my best friend at work (I am a MF and he is MM). We have worked together for many many years. First affair for us both. It has made me realize that I DO have a sex drive, and a ferocious one at that. I am just not attracted to my SO anymore and haven’t been for many many years. My SO is honestly physically better looking that my AP, but I haven finally realized that after 30 years I honestly was never head over heels in love with my SO. I was young and with the progression of time we got married, had kids, bought the house, etc. and in that process I lost myself. But I have found her!!! My AP and I have the most wonderful non drama free relationship where we are both getting from each other what we are lacking in our marriages, and on top of that we have the kinkiest hottest sex that I honestly didn’t happen in real life. My SO would love for me to be that person with him (he doesn’t know she exists) but I just can’t make myself be that person at home. My SO is a great guy but had anger issues in the past, and it made me loose my attraction to him and I don’t want to get it back. I am not going to leave my marriage though (neither is my AP). To far along in life and to much to lose and to many people would get hurt. So we just enjoying being together 5-6 days a week and making out and fucking when we can. We tell each other we are the luckiest people to have found this and no one knows, no one is getting hurt, and we get to have the best times of our lives.
