Not pregnant because of this

My husband doesn’t have a strong sex drive. We do it like 2-3 time a month. I think he has low testosterone and doesn’t do anything about it. Makes me question how badly he wants a kid. Clearly not as bad as me. It’s so depressing and disappointing. I try not to make sex a chore these days with TTC. But omg its always been this way and we are trying to make a baby here. Get it together dude!
