Started crying during sex :(

I'm 38W4D and was so uncomfortable I started crying in the middle of sex! My husband is well endowed and it just hurt, plus my hormones are raging and I'm just so ready to have this baby. I feel terrible though because I probably scarred my husband for life.... 
It's hard being a wife and FTM and trying to please your husband while dealing with the stresses of pregnancy and all the stress if puts on your body especially these last couple weeks!
