UPDATE: hubby never last more than 2 minutes

So I love my husband more than anything in this world and I wouldn't want to cheat on him but he doesn't last more than 2 minutes during sex sometimes I don't even get a chance to cum and I just smile and act like it's okay I keep wondering if I should buy a dildo so I can finish myself off after he's done but I don't know I'm confused and I'm afraid to talk to him about it because I don't want him to feel less of a man! LADIES HELP!!!!! 
He's uncircumcised so after he cums his foreskin get really tight if we try to have sex again or if he keeps going after he cums it rips his foreskin and no sex for another 5 days
UPDATE: so I talked to hubby and we had the best sex after!!!! Lots of foreplay and used a dildo to get myself started and he literally snatched my soul
