When I was 12 (17 now) I was in an accident that left me badly scared from burns on my legs and arm (Arm doesn't bother me) and I'm still a virgin and I worried that my first time that he or she will see or feel my legs and freak out and not want to have sex anymore or get turned off by me or tell their friends that I'm gross or some shit like honestly ive considered just waiting till I was old enough to get an escort or something instead for it so I don't feel judged or gross, any advice?
Don't go to an escort. Wait for someone that really cares about and/or loves you. I know it's seems different because you have the scars, but almost everyone has something about their body that makes them feel just like you do. Some flaw that they're certain will cause them to be rejected and unwanted. If someone loves you they won't look at those scars and see something gross, they'll see a piece of your history and they'll love it and accept it. One of my legs is partially paralyzed, it's atrophied and thinner than the other and kinda weird looking, it makes me walk with a limp and sometimes I have to wear a brace. I was terrified that no one would want me. You know what? Despite all that fear, it has never been an issue for anyone I've dated. Not even once.
I second Femmeme's advice. Wait until it is with someone you care about. If you are worried about it, tell your potential partner about it. That way you don't have to stress out about it as much.
im a virgin too, and im a guy, oh well. the way i see it, if someone cares deeply about you, they would never judge you, especially for physical stuffs. escort, however, has the possibility to go around and tell that "yo last night i got something blablablablabla" meanwhile your future loved one will love you enough to get past that since it makes you who you are
(*hug*) don't worry hon! no one will care about your scars, you will find someone who thinks you're the most beautiful thing in the entire world. if someone does care, you should not be phased by it. that person is just a jerk.
A suggestion: if you think a relationship is going in a sexual direction, then tell the person about the scars before things get too far. If necessary, show them the scar and tell them the story about it. This takes the pressure off everyone by removing your worry about the scars and any potential surprise that the person may have by seeing/feeling the scars in a moment of passion.
