First time, in the woods😁😶😶

Okay so I've been talking to this guy for a couple months (3-4) well one day I got up the courage when he asked me to hangout I walked across the street (to his house) to have sex well his parents were home he said lets go for a walk I was like okay 🤔 he told me to take him somewhere I had never shown anybody I was confused but I took him to the spot where I smoked (weed) for the first time he started to kiss me and play with my ass and rub in my thighs it felt good so of course I was wet 💦 he started to unbuckle my belt and he started to finger me and this was the first time anybody had fingered me so I moaned a little while he was kissing me and he bit my lip and that is a major turn on for me 👅💦 well he turned me around and bent me over well it's my first time and I'm tight so it hurt a lot he said it will be easier for me if I got in my knees so we did and I bent over and he positioned my back to where I was comfortable and he tried to stick it in again it hurt but he didn't go all the way in I couldn't take it I turned around he said it was okay he made me feel so comfortable he started to play with my hair he told me I was beautiful and that we had to take it little by little he said I bled and I was so embarrassed he told me it was okay and it was normal he wasn't freaked out at all ❤️❤️ why did it hurt so bad ?? Was I doing something wrong ??
