i would talk to him about the whole subject of touch in therapy asking him how he views it and let him clearly know you aren't comfortable with things progressing any further. i think you would be smart to trust your gut on this. see how he responds in a discussion and if anything doesn't sit right with you then i'd find a new T. i think the part that concerns me is he was giving you side hugs until you shared about CSA and then he wanted to give you a real hug which i am assuming was front to front. he may just have looser boundaries and see touch as being therapeutic but that really needs to be communicated so there is no confusion. personally, i think it is best if you are the one asking for touch rather than him initiating it. i'd let him know that if you feel the same and that if you want touch you will ask.
