is there anyway for a girl to widen up her vagina so that when she does have sex it will not hurt?
I was actually recommended to masturbate with a Dildo or vibrator (or if you have none of those a banana or cucumber with a condom on), this was from a different forum. That was what I did to 'stretch' myself for sex a little. However I wish I hadn't done it and I don't recommend it, I would have rather done it all with my boyfriend, including the massive amount of pain. Sex still hurt a little though, but I didn't cry during it etc. Some people say to masturbate or have your boyfriend finger you with at least two-three fingers, to make the pain slightly less.If you are thirteen though, I don't recommend having sex, I don't know how old you are, your name just had 13 in it.
Using a dildo or a vibrator is a good suggestion because it gives you an idea how it will feel (penis in the vagina). However, the vagina is a muscular canal, so it can't really be widen or stretched out because the vaginal walls touch each other when there's nothing there. The only time when the vagina becomes less tighter is when you give birth.
If you are worried about the pain, I'm afraid there's no real way of not making sex 100% pain-free (not that I know of at least). Like moonlight said, during foreplay, your partner can incert his finger to help you relax a bit. You can also use lube to lessen the friction. However, I did this with my boyfriend and there was still a bit of pain. If it will ease your mind a bit, it's not that painful that you are screaming or crying. There's a bit of pain that will only last one or two seconds tops. Soon after you will get use to it.
But I want to say that you are only 14, so hold off from having sex until you're older.
wut i did was SLOWLY have mt bf work up to 3 fingers...worked well 4 me....and i wouldent say that sex was "painful"...id just say that it was a bit uncomfortable.
