I am a 22 male. good body weight, have started hitting gym recently as well. But sex with my girlfriend has declined the last 3 times. The problem is I can’t stay hard for long, she cums but I cannot finish the last couple of times. I am starting to feel like less of a man. I thought the gym would make me Rock hard but suddenly it’s doing the opposite. The only thing I’ve changed recently is being on a calorie surplus and not eating as healthy as I should since I’ve been bulking. I do watch porn, but that has never stopped me before and it’s not an excessive amount. Please help me out or give me ideas about what could be causing this. I love sex, and we usually have a really great sex life
