Trying for baby number 1 but I’m too scared to initiate sex

The title pretty much says it all! But I’ll give a little background information.

Me and my husband have been together 5 years and trying for baby number 1. We used to be in a long distance relationship and our only form of communication was texting or calling.

We’ve been living together for almost 4 years but I still struggle to initiate sex. I’m pretty good at sexting and sending pictures but when it actually comes to starting it physically I get so nervous and work myself up so much that I end up crying.

We’ve spoken many of times about it. About how it’s making him feel like he’s not good enough or that I don’t want sex with him. The struggle is that we only have sex around once a week and I know that’s not going to work if we’re TTC.

Does anyone have advice for to me to either start initiating sex or how to feel more comfortable telling him that I’m ovulating?

We both want a baby but it’s just difficult when we’re not very sexual people. I don’t want it to feel like a chore to him!

Thank you in advance.
