Can you feel your baby when you have sex ?

Last night my man and I were having sex. I was laying down downward and he was on me, getting it from the back. I felt something on my lower stomach I’m pretty sure it as the baby. I felt a pressure and it was ticklish. I was dying while he was going. It just felt so funny. I got scared though thinking that pressure of him on me could hurt the baby? Is that possible ? Had this happened to you ladies ? I’m only 11 weeks. My tummy hasn’t grown at all.
