“My boyfriend and I were messing around and ended up grinding against each other in our underwear. Could pre-cum get through the fabric and get me pregnant? I’m a virgin and slightly paranoid about pregnancy.“
To answer your question, you are not likely to get pregnant from the activities that you are describing. The more important conversation is how old are you and your boyfriend and have you talked about using birth control.I want to encourage you to make an appointment with a health care provider who can give you information on birth control and can also provide information on protection from sexually transmitted infections.
