I have a question for the men...

Je

My husband and I have been having sex with each other for almost 3 years. The other day during sex, he gets obviously hard and I go down on him for a while. After a bit, I hop on like normal and go to town. Nothing happens. I start pulling tricks: moaning, dirty talk, twerking, the whole 9 yards. Nothing. This is really odd because he normally cums pretty quickly. I start to think I’m doing something wrong and he tells me “it’s not working”. So I hop off and just lay in bed on my phone. To my surprise, he grabs me and flips me over to go doggy style. Still nothing. I’m moaning his name, telling him to pull my hair, and nada. This goes on until I literally can’t take anymore. He’s still hard, but my vagina feels like it’s got rug burn and frankly, I’m no longer into it. This is probably 20x longer than we’ve ever gone and he just can’t cum! He says he has no clue what’s going on and we’ve never had this issue before. Anyone ever been through something like this before? I think we’re both nervous to try again :(
