Is it normal to be tight down there?

Don’t worry, it’s normal. It hurts most girls until they are stretched enough to fit a penis. Just be gentle and use a LOT of lube. Ask him to massage you gently and work slowly from one finger to two fingers, (or you do it yourself) day after day, and when you’re stretched enough to fit his penis, then go for the real thing. But remember - fingers that go in there need to have their nails clipped and filed; use a lot of lube (I recommend Astroglide, it’s the best choice), and RELAX all your muscles. It will still hurt the first time, judging by what you’re saying (I was the same by the way), so all you can do is prepare yourself, practice stretching and relaxing and know that it will take some time and exercise before it stops hurting. For me it took several months of sex after the first time to stop hurting, but maybe it will be better for you… And really, I can’t stress enough the importance of lube… I wish somebody had told ME back in the day, haha… Good luck and have fun! :)
