You’re doing pretty good then. I mean, I hear about some couples in their 30s who don’t have this condition and barely have sex more than once a month.
If she has stuck with you this long without complaint, then you’re probably doing okay. Not worth ruining it over sex if everything else is okay in the relationship. And I’ll use the word “okay” as if it’s a good thing because after 6 years, if there’s not constant strife or boredom, then it’s going relatively well.
My suggestion would be to get a prescription and make like you’re 16 again once a week. That should be infrequent enough to not build a tolerance and may help with the potential fibrotic effects of lack of bloodflow. It seems Cialis is more popular among guys on this forum, but it never seemed to work for me personally, even in the less dysfunctional past.
