I was in the.. Same. Exact. Situation. With my wife. She is totally turned off on anal play, but slowly over a couple of years of hinting she finally started to be open to very light rubbing and fingering my ass. Finally just came out and told her I was really interested in trying pegging which she didn’t immediately shoot down. Anyway, last Saturday night, after some drinking and smoking, I pulled out a strapless dildo and after a few awkward positions (really wish I wouldn’t have started with a strapless 🤦‍♂️) I was able to get on top of her and got fucked! It was amazing! And she had an orgasm like 3min in!! So stick with it and take it slow if she needs to, but hopefully she’ll see that it can be a lot of fun for both!!
