Concerning?

My SO and I have been trying, pretty much since our wedding (8ish years). Not really trying just if it happens, it happens kind of thing. A few years ago we did have some testing done and were going to do some rounds of IUI. Well, More life got in the way and we never made it happen. The past 3 months have been rough. We haven’t been having sex like we use to (maybe once or twice). We talked a little about making an effort to save money to do at least a round of IUI. My concern is now he informed me the last 2 times he tried to pleasure himself (which I’m fine with, I know he does it) he said he felt like he orgasmed but there was no cum with it… his is type 2 diabetic but not sure how concerned we should be.

Any advice?
