kinks

i have some kinks and my boyfriend knows but i’m a little scared to bring it into our sex life. i called him daddy once before and it made him go crazy he started pouding lol. but i’m still hesitant and don’t get me wrong i still get turned on a lot no matter what but i know that intergrating my kinks into our sex would make it a lot more pleasurable and fun. i need some advice on how to boost my confidence and how to talk to him about putting some stuff in. thanks!!
