Hey guys, recently I've struggled to last more than 3 or 4 minutes when having penetrative sex. Oral is fine, I can last forever and really enjoy it, but I almost feel a slight stress coming on when I readying myself for intercourse, for context im 55 years old. I'm still enjoying myself but I find I want to enjoy foreplay for ever longer percentages of a session, as I know that once I commence penetration, it's going to be over relatively soon. Does this happen to anybody else and is there any advice you can give me?
