First time advice??? (Long post)

Mani • Sophomore, Gay asf🌚, tryna find some more friends honestly. If you want my social media, just ask🙃

So me and my gf have been together for 9 months now..(I’m 16 and she’s turning 18). And since she’s a little older and she’s done a Lot more than me. We’ve talked about having sex and everything, but I’m gonna be honest.. I can’t guarantee that I have good pussy and i don’t wanna get embarrassed or anything..like the taste of it. and Ofc i don’t want her to break up with me for it or anything. I mean shes aware of why i won’t have sex with her but i never go into detail. So does anybody have some advice or solutions for getting over this fear???
