hey emz1 just to let you know i too have the same problem. i have anxiety issues and these Intrusive thoughts of sexual nature on family, realives and others have been bothering me for quite sometimes now. worse still its clearly manifesting in my eyes i have very creepy eye contact you know like looking at inappropriate places at inappropriate times in full view of others its out of control and it is making my life miserable. for many years now i've been suffering like you i dont think i can tell my family, friends no way and because of this i am losing just few that i have and i dont make friends being ashamed of myself. as far as Krama is concerned mere Thoughts dont amount to Karma eg., Karmendriyas or organs of action are arms, feet, speech, genital and the excretory. mere thoughts will not amount to karma i believe.
