new relationship and kinks.

so i just recently got into a relationship (i’m 17) and we’ve had sex multiple times already. i’m pretty shy, especially when it comes to sex because before him i was a virgin but i do know for sure that i have some kinks. we’ve been dating for only a few days yet we’ve had a thing for the past few months. just wondering when would be the right time to either bring up my kinks and ask if he has any, or try them with him? (i’m really into being choked, not hard but the feeling is great) because he put his hand near my neck and i just wanted to move it to around my throat. also, i’m a squirter and i haven’t told him but when we have sex, it’s like i’m about to orgasm but i can’t because i’m trying not to squirt? anyways advice would be great, thanks ladies! x
