My husband I are both 49, we’ve been together since we were 22. We started having sex with other people when we were about 24. We’ve very rarely had 3 ways, maybe 1 per year ....... we both prefer to have sex with other people on our own ........ we’ve both had 3ways with people that didn’t involve each other ......... we’ve go to saunas here for sex and to many sex clubs in Europe like L’Impact in Paris and Laboratory in Berlin ..... have been to Point 202 and Club 117 in Rio many times ...... to Prague for escort clubs like Pino and Escape which are now gone ...... it’s never been a problem at all between us ...... in fact in the last 10 years, we’ve mostly only had sex with other people ...... and we get along GREAT. We even have an 8 year old son I had with a surrogate and are great parents to him.
