First time !!!

So I’m currently on at the airport on my way to Vegas for my birthday weekend with my bf . Y’all know I’m gonna get some birthday sex 😅 He actually surprised me with the trip. He’s a very kinky man and I’m not that kinky . He’s been asking me to try anal with him and I’ve been very hesitant about it so to thank him for surprising me with this trip I wanna do it lmao it’s a “you know what yeah..okay I’m down “but I’m scared not that I don’t want to try it but because I heard it hurts lol what if he can’t put it in and he’s gonna force it in lmao he has a big dadonkadonk but I’m about to pray for my ass 😂 any tips ladies ! I have 3 hours left..the clock is ticking
