"It also doesn't help that he has a huge issue with premature ejaculation (basically intercourse lasting 30 seconds is met with "Wow, you lasted really long that time!"). I mean, I can be patient "

Hi, one thing I learned is to never mention that he doesn't last long enough. I'm sure you know that and I'm not trying to make you feel worse, its just that I was like that too. I never enjoyed the actual "intercourse" part, for a reason, but once I finally was enjoying it I realized he just wasn't able to last long enough. Big mistake to tell him that.

If you are just upset because the actual intercourse itself isn't getting you to orgasm, I think you are part of a huge club. I never did.

Oddly, don't know if it would help, but he tried the viagra stuff, even though it wasn't that he couldn't get it up, it was that he couldn't last long enough, and that helped him to keep it up much longer.

I hope you can try to just enjoy each other, and be thankful you have someone there who loves you.
