IUI after difficulty w/ejaculation

Has anyone in this group tried IUI because their partner has “performance anxiety”? All of my hormonal levels appear fine (although I haven’t had any further fertility testing) and no other obvious infertility red flags (endometriosis, issues w/my cycle, etc). However I’ve been off of birth control for over a year and a half and no such luck. However, when we do have sex my husband struggles to get off. This has been a constant since we’ve been together for 8 years. We probably only have sex with ejaculation 2-3 times per month MAX! We have sex more often but he doesn’t cum. The next step is getting further fertility testing for both of us; however, I TOTALLY realize that our chances have been VERY low at the rate we’ve been going.

Has anyone else had this experience and tried IUI?
