Husband not interested in sex

Anyone going through this that can offer any support or help? My husband is not cheating, does not watch porn and I’m pretty sure that masturbation is not an issue either. I truly feel he just has very low sex drive. I know most people are opposite, but for those that have any experience with this I’d love to hear any encouragement to what may have helped . We currently have a sexless marriage and I’d love to see this reversed. He has excuses every time i mention sex (not feeling well, tired, etc.). He got his semen tested last year when we were TTC and all was fine. He promised me sex today but warned me it may not last long (already making up excuses - I don’t think he meant bc he would ejaculate fast either. I think he meant he wouldn’t be able to stay hard maybe...).

I had a baby early October and that made it so I was too busy to ask him for sex, which I’m sure he liked. Our marriage is going great right now except for that. I hate to stir things up and cause issues which is why I’ve been avoiding this and just letting the excuses fly. Until now, when I realize this needs to be addressed but I don’t want to cause any problems or fights 😭 (it has in the past). I love him and please don’t say divorce, I’m really just asking to hear from the small minority out there that may have any experience with this.... 🙏🏼

P.S. I don’t think wearing lingerie will help either, unfortunately.

P.S.S. It’s not because of the baby either, he was like this before baby too. We tried for a while to get pregnant and it caused a ton of stress (most likely bc it was forced sex), and we eventually ended up doing <a href="https://glowing.com/glow-fertility-program">IUI</a>
