2-Pump Chump

So my husband and I have been together for 5 years now (married for 2 months) and from the 1st day we started having sex, he has NEVER been able to go longer than 5 minutes before he cums. He is so fast!! I don't think it's a "foreplay" thing because we very rarely foreplay. I mean....I've always joked around with him and said "yeah, it's this GP that gets you every time"...hahaha
But poor thing gets so frustrated with himself when he gets off so fast and I am still waiting for mine. I feel bad for him. Is there anything you ladies recommend he do to give him more stamina so he doesn't get off so quickly??
