The second girl I had sex with, ha back when I used to keep count, gave me her V-card on my birthday. I made love to her as we were in love. You can read techniques on the internet on how to gently stretch it out some with your fingers. I did that, ate her out till she came and then slowly worked my way in, I'm talking about it took an hour and most of that time was right at the head.
If it hurt her to much I backed out and then slowly worked up to that spot again. After an hour something incredible happened. I could literally feel it slowly open up and was able to goo all the way in. Instead of ramming it in and it hurting her I took my time. Instead of tearing her hymen I stretched it. To my surprise it felt really good to her. She came! We would have sex 12 more times throughout that day!!! The next morning we were in the shower and she wanted sex again but my dick was so sore and sensitive from squeezing into such a tight hole I couldn't do it haha. I think I was 7x5.5 at the time.
She's told that story to all her girlfriend and from what I hear they all wish their first time was like that. They were very jealous of my ex. You can give that experience to her too
