I need help

Ladies—- I’m dating a guy I really like. He wants me to give him head…………. I’m cool with that and I wanna do it for him but I’m not super experienced in that arena, but moderately experienced. Here’s my “problem/s”

Please give me all the advice, tips, tricks, ETC.

1. I’ve never been with a guy who isn’t circumcised- he’s super clean so that’s not a concern for me—- however, I’m scared I’m gonna hurt him because I’ve never given head to a guy who isn’t. Like what are the DO’s and donts and how to’s???

2. He last longer in bed than any guy I’ve ever been with. (2-3 hrs) And don’t get me wrong— I LOVEEEE IT. But that being said, I have never given a guy head and him not cum. I made the mistake of telling my partner that early on in the relationship. 🥲 He’s never cummed from head, that’s just something he does before actually having intercourse he said. So now I’m nervous because I set this expectation that I’m “good” at it early on and feel like I may not can live up to it … because let me tell y’all his sexual performance is top tier. He also is a bit bigger than most men I’ve given head too. I wanna make our date night tomorrow the best sexual encounter hes ever had (or at the minimum the best he’s ever had with me). Please help settle my nerves and give me all the tips and tricks.

3. He said he likes dirty talk—— I feel like I don’t know how to dirty talk and I don’t wanna ruin the moment saying something I think is sexy and dirty and then just turn him off.

Here’s some things he has mentioned he’s into

Ex: slapping my butt hard while we’re having sex, slapping my face? (Gentle unless I can handle harder he said). He also has put his hand over my mouth and told me to shut up while we’re having sex so clearly he’s into that. Don’t get me wrong—- I’m absolutely loving it bc he’s also gentle at the same time— but I feel like I’m not good at sexual things tbh and I’m feeling insecure. Please help!
