Erection help

Okay team, I’ve never come on here for advice, but I’m stumped and could use some support...

My husband and I are in our early 30’s and have been married for two years. We have known eachother since junior high & have a great marriage. No kids yet.

We have had a little issue for a couple years now and I don’t know what to do about it or how to address it. When we have sex, my husband has some trouble sustaining his erection. He either has to finish fairly quickly or risks losing it. If I suggest slowing down to make the session last longer (having him pull out for a second, etc) he sometimes loses the erection. Other times, he loses it and cannot get it back to be able finish. Most of the time, he just finishes quickly (and yes I organism too), so we don’t have to deal with him losing his erection. The only problem with this is, it makes for quick, not so passionate sex.

I know this is not an issue of him not being attracted to me. We have had lots of conversation about it because it does tend to make me feel insecure. I really think it’s something he can’t help. He says sometimes it just happens and sometimes it’s because he feels like I’m not into having sex.

I don’t know what to do about it or how to possibly suggest that he asks his doctor about it. I don’t want to ruin his self esteem or cause him to feel embarrassed.

All suggestions welcome!
