I give up. You want to force your opinion contrary to Church teaching. In this response you have reiterated exactly what I said previously. You are reading into the Catechism something which is not there. Sexual pleasure is ONLY sexual pleasure with an
ACT of sex!!
Desire for sexual pleasure is simply that, desire.
I can, as I type, desire sex with my husband. I am not experiencing sexual pleasure in that desire. (Gosh, I certainly hope not!

) My
desire for sex with my husband is, in my case, an
ordered desire since it is A. heterosexual, B. for my husband not someone else, and C. ordered toward procreation and unity (not contraceptive.)
If a, b, or c were the opposite of what I have listed they would be
disordered desires, but not sinful. Now if I were to ACT on any of those disordered desires, I would be sinning. I don’t know how many different ways to explain this to you. It is not a sin to desire the same sex in a sexual way. It is a sin to entertain that desire into some form of ACT, (i.e. a fantasy, or worse, engaging in contact.)
It really doesn’t sound like you want to understand Church teaching. It sounds like you want to say the Church is wrong in her teaching. If you think the Church is wrong in Her teaching then we will have to disagree. I am a die-hard Catholic. I believe the Church is free from error in faith and morals.
If you suffer from scrupulosity then I am sorry for your burden. We are NOT sinning any and every time a bad thought pops in our heads. If that were the case, none of us could ever leave the confessional! A thought or act must be
chosen to be a sin.
