Your feelings, my feelings or anyone’s feelings are not the best guide to what is morally right. After all, there are people who can murder, steal or deal drugs and not feel in the slightest that it’s ‘wrong’ to do so. ‘Following your conscience’, unless your conscience is precisely in tune with God’s teachings, is the short road to ruin.
And how does God teach us? Through the church, which He gave the power to bind and loose. In a nutshell - if your ‘conscience’ isn’t in line with church teaching, which comes direct from Christ through the Holy Spirit, guess what needs adjustment. Hint: it ain’t the church teaching.
God, funnily enough, has His own ideas about the true purpose and meaning of sex and sexuality, among other things. He shows us what is right, what uses of the sexual faculties are in accord with His purposes for them, through the church which teaches with His authority.
And the rules aren’t there to prevent us enjoying life, rather they’re there to HELP us enjoy ETERNAL life - which is far more important.
Surely there are times in your life when you’ve put aside what’s superficially pleasurable - tv, going out or what have you - to concentrate on what’s really important. You’ve probably done so in order to study for school, for example.
Don’t you find that doing what’s right in that way brings its own rewards - better grades for one? And don’t you find that they last much longer than any fleeting superficial pleasure you’d have had from going out or wasting time in front of the tv instead?
See God wants what is REALLY best for us, and makes us give up superficial distractions and concentrate on what will really enrich our lives both here and eternally. Not just what makes us feel good for a short time and serves little or no ultimate purpose.
