I’m a male, 22 years of age and I’m having issues keeping a strong erection even around my girlfriend. I exercise all the time, I can run 10 miles easily and I’m just fit physically. I don’t drink, don’t smoke, and I’m not gay. I’ve recently stopped watching porn about 2-3 months ago. Right now my girlfriend especially is concerned about it and I don’t want her to ever question things like if I find her attractive or if I’m into women, because I am. I really could use some advice
