In a relationship of several years. Both early 40s.
Sex has never been a massive part of our relationship, we went through a period where for various reasons we had very little sex (partner confessed porn addiction - which he has since successfully sought help for, also health problems on both sides) anyway we're getting over that now. Sort of. Except the last few occasions we've tried, he hasn't been able to maintain an erection during penetration.
He can manage 'by hand' (I have never been able to do this for him by hand or mouth, never an issue with previous partners so I don't think it's all me) himself so its not like he doesn't get hard or anything. He has said it might be related to medication he is on, but he's been on that same medication for a long time. He says he has to focus 100% and if he doesnt then he loses it. However this makes it harder for me because I now feel I cant say anything or move or whatever because if I distract his focus then it's game over.
I would say this focus issue has always been there but not as bad, so he would lose erection but get it back once or twice and eventually after 45 mins-an hour he would get there, but not now.
We talked about seeing his GP and he seemed receptive but I'm not sure if this is a physical issue or if its more psychological...is it just our age?
