Hello, please answer these questions. I did masturbation for a while. I did pillow humping without underwear, however I did not insert anything into vagina. Can my hymen be broken by that? Sometimes I felt in my stomach, but there was no blood. One time there was a tiny pink liquid almost invisible. Can I tear my hymen by that? If I do clitoral masturbation with pressure can it cause hymen tear? Thank u.
