My boyfriend suffers from ED but how do I/we tell if it's from porn over use, a medical issue or just an age thing (he's in his early 50's). I know he can bring himself to orgasm through masturbation with or without porn but nothing I do orally or manually seems to get him there. He says it feels amazing but still loses his erection even while I'm doing it. Sometimes he can get and then lose his erection multiple times during our sex play. He can have an erection while I'm stimulating him manually and then lose it if I stop for 10 seconds.
I've read on the Your Brain on Porn site guys saying their penis feels numb so does the fact that he says oral sex feels amazing (even though he loses his erection) mean it's not a porn thing at all. I know that he watches porn and/or masturbates several times a week and that the type of things he watches has escalated to what I would call a more "extreme" porn.
I should add I don't actually have an issue with him watching porn, unless of course it is making it hard for us to have a healthy and fulfilling sex life together. I think being able to share an orgasm with your partner is a wonderful and bonding thing.
