I got with a girl and the condom ripped and I didn’t realize it and was going basically raw for a solid 20mins and I came close to Cumming several times but did not cum inside of her or outside for that matter. Before this happened I came once in the morning, once before I went to her house, and twice at her house before this incident happened. I’m 16 so if she was pregnant it would be really bad. Is there a chance she is pregnant? What can I do to prevent this in the future?
