I live your situation every day... My husband has not only a thick but long penis. Some positions are less painful than others. Sex with legs down always hurt less, spooning is also very good cause it cushions the penetration, also laying on your tummy flat legs slightly closed. These should help you for now, your being on top will hurt even more, beleive me. The trick to being with someone with a large penis is not to shy away, yes it hurts, but your vagina will grow used to the size and eventually you will love having sex with your man, sex with him will be the most mindblowing experience you have ever had and the positions will become easier and more enjoyable. On the plus it gets alot easier when you have your first child.....oh yeah, lots of oral sex helps, it gets you so excited with anticipation that the penetration is easier and more enjoyable.....Good luck.

spooning is nice because your butt will cushion his thrusts, and you still have petty good control over how deep he goes by how you angle your hips. plus it maks it easier to play with yourself and stay super aroused!

try to relax and don't let it in your head that he's going to hurt you before you even get started. that will only make your vagina more tense and make you less aroused. the more turned on and relaxed you are the better!

try the missionary with your legs straight down and almost completely together, your knees locked straight, (your heels almost together and toes pointing outwards) and his legs right on top of yours... he may take a minute to find is angle and rhythm but he will figure it out and you will both LOVE it! his penis will rub your clit, your vainal opening will be pleasantly taught, and he won't be able to pound on your cervix.

On your knees and him underneath you!

Also, lots of foreplay to get you wet and warm!

Try very slowly him going in!

seriously, i had a similar problem with a gf-not beacuse I'm so big but because she hadn't had sex in literally years. work with a didlo-there're some mighty big one's out there-until you can accomodate him. Make sure everything's good a moist.

he'll love it when you can take him in deep.

Lying flat down on your belly with your legs straight out might help. As well, it may help to practice with a toy slightly smaller than him for a while. My guy is bigger too and when we first slept together (or tried to lol) he couldn't even get completely in me cause it hurt so much for me. I practiced with a dildo for a few weeks and it made things much better. Practice makes perfect, and the vagina is flexible and elastic. As they always say, if a baby's head can fit through there, a man's penis (even a real big one) can fit in there. Like any muscle, it just needs to be exercised. Good luck! :)

Missionary, but with your legs on the inside (almost closed) and his on the outside. You could also try with him sitting up (like on a chair, or against the headboard) and you on top.

we had a similar situation, for us it helped when she did it more, it strecthed her out. We came to an agreement that she would have sex at least twice everyday. Being that I travel for work regularly this meant her having sex with other men. Once she agreed and started having sex with other men our sex life became incredible. email me if you want more details.

Very good common sense info.
Some pain can be psychological and some can be a sign of a physical issue you need to get check with your OB/GYN.
