i don't know how to express my feelings and anxiety to my therapist

i've been in therapy for 3 months and we've talked about a lot of things but i feel like i can trust her more and i really want to talk about some extremely personal stuff that i haven't talk to anyone about but i know i should really just get it all out and stuff but i don't know how i really hope someone can help me and i hope people actually see this. i am going to talk about my sexual feelings and desires and how they make me feel and talk about my hanger issues and other things that i just don't know how to express or bring up i don't know how to talk about this stuff
