I've had surgery on my hips like 5 or 6 times and I have scars on both my legs from that. On one side it's not very noticeable, but on the other it's pretty clear(because I've had surgery on it like 3 or 4 times) and it's sensitive to touch. Well because of that scar being so sensitive I just shave around it and leave hair over the scar(it's not like it's a really big scar...they're pretty small...like maybe a inch or so across and wide on the bigger one).
What I'm wondering is, would that bother any of you guys if a girl did that?
Don't worry about it. First of all, at your age, there shouldn't be a lot of guys getting that close to your hips. Also, since you are still young, your scar will very likely fade away. I knew a guy who was in a car accident when he was 15. He went through the windshield and his face was sliced up VERY bad. He had big, raised scars all over his face and neck. By the time he was 25, they were very faint. I saw him recently (he's 41 now), and I couldn't even find the scars.
Try removing the hair with depilatory cream instead of a razor.
