I need help checking my virginity
I'm almost 18 years old. I've had a three-year relationship and, during that relationship, I used to have sex with my boyfriend without a penetration; I mean his penis only pressed on my vagina without penetrating. So, about a year ago, I bleeded while having sex and that wasn't period... But no intercourse ever happened between us. Now that we broke up, and since I live in a western society, I'm scared not to be a virgin.
1. How can I check my hymen by myself?
2. Should I see a doctor?
3. If I weren't virgin, would this be obvious to my future husband?
I'm really worried and waiting for your reply very soon.
