I self harmed for two years. I began starting a new coping skill that has been really effective; eating. Although, I'm worried because I had a slight eating disorder before, eating might draw me back in it agaian.

i am 23 year old and doing a job as a designer.
now a days my feelings is very dirty and i start doing fantasy about dirty things.
i can't explain what should i do now ?

Hi guys ,
This is pretty awkward to me talking about anything related to therapy to anyone. I've been seeing my therapist for a month now , we had 4 sessions and 3 walks so far. What i wanna talk about is how i can open up to him and not feel so stiff around him and end up regretting not saying all i want or any of it at all. He says we have a good relationship but it’s different for me. I feel really disconnected. I have so much to tell him but it always ends with me not saying what i REALLY wanna say , especially when we have a walk. There’s that thing i do when i feel "bad" , i pretend that i'm telling him what i'm feeling so i calm down. Maybe it’s the reason i have nothing left to say ?
The reason i'm trying to find a way to be more open is that i feel forced by myself. I’m regretting everytime i see him and end up not saying what i feel at all , and i don’t wanna drop therapy. I really really need it. I had a really unpleasant event by the time of our 3rd session and it made me realize how lucky i am to have a therapist at all. I wanna start fresh and on good terms with him. I wanna trust him enough to be comfortable around him to make our process better and not feel pushed. And he’s just a nice person idk what’s wrong with me
I want to want to get better and not feel so forced by myself.

Obviously I'm going to know the answer, it's just I want to hear another persons opinion.
I'm a 16 year old girl and I like fantasizing about things, sometimes it's actually meaningful and sweet, then sometimes it's just dirty sex with this guy I have been dreaming about lately.
I dunno what drives me, but it turns me on so much to be "dominant" over the person, not like "chains and whips" (No, not at ALL) but in a way that the other person can't say "no" to?
Who knows, I'm pretty sure I'm a pervert but I don't really know why or how I became one.
(^-^)

I'm not sure what I should do, I had a dream and my therapist was in my dream, by the way the dream was NOT sexual. I am wondering if I should tell him about my dream or not????
