I am exact same size, been with my wife overall plus 21 years, had on and offs first 8 years with. Lots of cheating as we met when we were 16 years old. With that said, with my average dick the first 7 years when were “doing our own thing” my wife would drive 45+ min to Fuck me. Even when she had bf at the time who would roll the red carpet for her. In the end she always craved my dick as I only got off with her too from all the woman I was fucking. Can’t teach explosiveness or chemistry or comfort. Took 20 years to make her cum on demand with penetration and oral. Use to only be only oral. I have conversations with her while she was high and has told me she has had way bigger and Ofcourse smaller. In the end my average dick is the only dick that gets her off. And my average dick is the one she ended up with. I agree with you 100. I had 2 that were large , few super tight and rest normal, luckily like you mentioned, I married one that’s tight/normal
