I do not normally masturbate, maybe once or twice a week or two, this time I masturbated once two days in a row then the third day i got a ha****b from my girlfriend. So this is 3 days in a row I have ejaculated. It is exactly a week later. The first day after i could not get an erection, since then i have improved in my erections, it seems to be pretty normal now, but it does not seem to be as hard as normal, i cannot tell if it is as hard as normal and im overthinking it or something is wrong. Help?
