I wonder why it is that you feel that you should discuss your sexual preferences and predilections with a counsellor? Looking at your profile it says that you are "AB, DL, BF, DF, Sissy / LG, Little". If you are in fact all of these (and please don't think I am judging you or criticising in any way, because I most certainly am not) then I suspect that your predilections are pretty deeply ingrained; and as Dogboy said in an earlier reply, these fetishes, as with many other unrelated ones, are simply not something one "outgrows".
I know from personal experience just how hard it is to give up a fetish, when I was younger, I tried more than once to give up my DL tendencies; the fact that I am here now posting an answer to your question shows just how successful these attempts were. I have long since come to terms with it, given up trying to overcome my ingrained desires and embraced them, and I am now much happier in myself as a result.
As others have said, unless the counsellor/therapist has in-depth knowledge of ABDL and related tendencies, then there is little point in talking to him/her, because they simply won't understand your problems.
