ocd,confused,please help

-i know this is long but please read-

Hi,I have been to a therapist and he has diagnosed me with OCD. However there are some things I don't even want to talk to him about,but I would like to share it on here and get some input,if this is normal ocd,etc since this is pretty much anonymous..I have had ocd since I was about 8,it pretty much started after i was pretty much molested (don't want to go into details) anyway i would have terrible thoughts that would make me feel EXTREMELY GUILTY,at this time in my life (when i was i was going to a private christian school and believed in god very much,and i was a very religious little girl,anyway there would be these unstoppable thoughts about God and I having sex..It sickened me,and it's so embarassing to talk about even on here..I was 8!And it was an uncontrollable thought I would NEVER want to do that..Anyway from then on it progressed,i had several different rituals that i had to preform all the time,I even had one ritual where i had to bump up against any thing i walked by,which lead to me having multiple bruises on my legs..My life has been pretty hard,and it seems like my ocd goes in and out,sometimes it's not that bad,and other times (like now) it's terrible,and i've realised it gets very bad when i'm extremely happy,or extremely depressed..Anyway I have a boyfriend that i have been with for 2 years,he is great,loving,supportive,etc and pretty much the best thing that has came into my life (my life hasn't been the greatest) and I am constantly worrying about something happening to him,and I UNWILLINGLY think about having sexual intercourse with other people WHICH IS SOMETHING I WOULD NEVER DO,THE THOUGHT MAKES ME SICK TO MY STOMACH,and i don't know why i have these thoughts,and after these "sexual intercourse" thoughts occur i feel extremely guilty,and i have to do my "rituals"..I'm sure by now any one who has read this is thinking "o'h my god this girl is strange" and that is completely understandable..I'm just posting this to find out if this whole guilty thing is normal,and what anyones input is on all of this..

Maybe i would,but this is going to sound stupid,but I don't tell my therapist because i'm embarassed,and because i'm afraid by telling him these things and admitting to it,that something will happen.

Well i'm afraid really,of admitting that i have these thoughts because i feel so guilty about them,and i'm afraid if i put them out in the open my boyfriend might leave me or something might happen to him,it's so stupid..

i'm afraid to tell my boyfriend..

i feel so bad about it and i don't think he would understand at all,and i think it would make him feel uncomfortable..

okay,but this is completely normal for ocd right?i shouldn't feel guilty?

well,i'm not really that religious anymore,in fact i don't really know what to believe..i just feel really guilty for thinking things like that,it's stupid that i feel guilty when i know it's just the ocd i guess,when our relationship/sex life is phenominal and were extremely in love,but i just can't help accept that it's not me,and that it's the ocd..
