Swollen and sore could this be from sex?!

Swollen and sore could this be from sex?

(im sorry if this might be a bit graphic....but i just want to know whats going on with it)

well about a few days ago me and my boyfriend had sex, and depending on how aroused i get, i get extremely "tight" so when this happened it hurt ALOT! It felt as though i was losing my virginty all over again.
well the next day we did it again, and it hurt still like it did the day before. so today when we wanted to do it, it wouldnt go in because it hurt SO bad. so we decided to stop and i could barely sit down. when i went to the bathroom to take a look at it...it was a bit red. i felt it and it was pretty swollen, and it hurts when i urinate. it also itches a bit. so i dont know.

is this something to be worried about or is it just sore because we have sex too much or because i was too "tight" that day?

thanks you guys just lifted a huuuuge weight of scared-ness lol....but yea maggie b....its not tight because its dry. honestly seeing as how we're all girls.....*whispers* im always "lubricated"...."naturally lubricated" lol.....so no its actually tight....but i looked at it again and it has cuts on each side near the hole. so im guessing thats why its itching.....so yep i guess your right maggie b seems my "natural lube" wont work outside the hole lol....
but yea
thanks everyone (^_^)

You are NOT abnormal, this happens ALOT!!!
I've had it happen to me, whre its all puffy and swollen and sore for a couple days, usually to be blunt after a long, sex session, (I said blunt didn't I), My suggestion first there is no harm talking to your doctor about it, it could be an infection, what with the itching BUT I doubt it, other then that
1. Make sure your boyfriend "takes it easy" for awhile if at all, he won't die if he doesn't have it for a couple days.
2. In case its something weird like your allergic to his ejaculate---this is possible, make sure he ALWAYS wears a condom---actually there is a possibly of allergies to the latex in condoms, no worries there are "natural" condoms available in sexshop and drugstores.
3. For goodness sake girl, get yourself some lube. LOL.
A good lube, KY Gel, and many other WATER-based lubes while definitely help (I'm sure of it) that "tight" feeling most likely is more like dryness. He can have some you can have some, and the party starts, lube can definitely improve a relationship, Hahahaha, honestly its true!!!

So that is my suggestions go to doc, use natural condom, get lube. Have fun grocery shopping AND enjoy your night, I'm sure you'll be thanking me in the morning (kidding)!!!
