I miss 🍆🏊‍♀️ with my boo

First pregnancy, 7wks & nauseated. Also had sex & its the first time that its been painful...I expressed the pain to my bf (father of 🌈 baby, hoping to stay sticky). His exact words were you were very tight (like the last pregnancy, miscarried at 5wks). He said I will ensure to be very careful, I can't hurt the baby but I don't want any discomfort for you. Ladies is there anything I can do? Feels like he's deeper than normal. Even did this little pelvic swirl to loosen me up lol....Bless his heart he's trying but if its too painful he stops the thing is I'd like to enjoy it again as well.
