Fast post-sex recovery
After sex/ejaculation, I feel quite drained and have absolutely no appetite for sex. This is normal. However, lately I have found that I don’t recover as quickly as I used to. It used to be that I would recover that day. But now I find that I am not 100% the next day! Consequently my erection firmness suffers. I’d like to be able to offer my girlfriend more.
Can anyone explain this? Should I be replenishing something? At the moment I take a zinc tablet post-sex.
