Sex question! Does anyone else’s man have this problem?

So my husband and I have been TTC for about a year now and unfortunately we’ve suffered two MC. He says he wants to be trying again and to always tell him when I’m ovulating but he acts like it’s a huge chore to have sex every day of my fertile window. We’ve been married 2 years and before marriage we would have sex every day sometimes even twice a day. And now I’m lucky if it’s once a week. I asked him about it thinking he wasn’t serious about having a baby, there’s too much pressure and even questioned indefinitely. He says that it’s more of a “performance” issue and says that now that he gets off inside of me, it basically “drains” him and it hurts his testicles anytime he gets off that much. So then I recommended that he pulls out throughout the month and then when I’m ovulating, we can do the deed but he disagreed and said he enjoys the orgasm he has when he gets off in me. I don’t know how else to approach this issue because 1. I’m not being pleasured anymore and 2. It’s hard to conceive when you’re not having sex any more than 3-4 times a month
