the only way it would hurt the baby is if it hurts you. he can't poke the baby or even come near the baby. the worst that can happen is he bruises your cervix. it will hurt for a few days but that's all. but if it hurts you to have sex and you get upset or anxious then that can upset the baby. just remember to take it slow and remind the new daddy to respect the babies home. (the womb) good luck in your pregnancy and I pray you have a healthy little one.
