Apparently the male average is 1.7 minutes. Bl to those girls.
When some1 keeps going and doesnt realise that some lube is needed? Ouchies.
I dunno. To me, bad sex would be like sex when you arent really involved with some1, but thats just me. No foreplay ( quickies can get excluded from this ), sex that just doesnt get you there.
Bad sex would be the fault of both parties, unless u are a completely HOPELESS sexer who has some weird fucked up penis that coudlnt possibly pleasure any1. If u arent enoying it speak up! and change positions. And for girls, bad sex no orgasm?
