It's "normal" in the sense that mediocrity is "normal."
Normal isn't a standard. Caring and thoughtful are standards.
I've heard lots of stories about lots of guys who apologize while they're cumming prematurely. They tend to be the butts of jokes among girls. If any of these guys knew the secret to making love to a girl--which is to focus on her pleasure, thus taking your focus off yourself and giving you total control over your ejaculation--there'd be a lot more happy girls, and a lot more guys who didn't have to say they were sorry just before shooting their load.
