I'm M, 65, in a new relationship, same age F. We've been completely intimate but have not shared intercourse, as I'm overweight. It's been 13+ years since I last had sex, so I've forgotten any aspect of the act. We are incredibly in love, like teens, and hope to soon consummate things. I just don't know if I'll climax in seconds, or how my old body will respond. I'm keen to learn what other guys find works for them to maintain control of their approach to orgasm. Appreciated!
