Sunburnt vagina - Do I need to be worried?

[aah123.livejournal.com]

Okay so I know this sounds bizarre but please help
I was tanning outside (where no one could see me) and I had my legs spread open
It wasn't more than about 30 mins total, and it wasn't consecutive. (I went inside every 10 mins or so)

I don't want to get skin cancer or something. I was also tanning yesterday and it was exposed but it doesn't hurt like it does today.

I didn't think it through. I don't know what I was thinking. But it felt good at the time.

I put ice on it for a while. I hope it will go away soon. This is really embarrassing. I thought it would be good to expose my entire body to sunlight but now I'm thinking maybe that sensitive area was not meant to see sunlight. I had my legs spread open really wide too :(

Is half an hour really that bad? I obviously won't do it again but do I need to worry or go to the doc? Please tell me this is no big deal. I tend to worry a lot. Thanks for your help.
