Married 20+ years....yes we have sex.
Sex life was OK to good but kinda boring. We did and still do things like bang one out standing up in places we might be seen, on a hike, etc.
I've done her 10 or so times in a store dressing room. Keeps it fun.
We started mfm with a guy we know a while ago, THAT has put our sex life into overdrive. When he's with us she gets fucked a LOT in 3 hours. Then she's horny as hell for days after so we fuck every day for a week.
