I just had sex for the first time with my boyfriend. I felt a pop inside me I checked myself this morning and I felt a soft skin wall. Is it my hymen?

Maybe. The hymen is soft tissue located right at the entrance to the vagina. It is often disrupted prior to the first time of having intercourse, through use of tampons, a finger or other activities. Was there much bleeding when you had sex and was that the first time you had sex, or the first time with that boyfriend?
