Sad 😢

So my husband hasn't really let me touch him since I've become pregnant. I understand he doesn't want to have sex because it makes some guys feel weird. I've known that from the beginning. I am a little over 6 months pregnant and he's only ever let me give him one blow job and that was months ago. I've tried so many other times and he just tells me not tonight I have a lot on my mind. I just don't get it. I feel very sad and insecure because of this. Do you think I have something to worry about or is it just me.Â
