dear friend, before this thread turns in the typical inter-denominational le ebin shit flinging battle, listen this
right now, you need God.. the problem of the right denomination will come later, now you need to start to get your life back on track
the sole fact that you came here for help is a step forward, because you admit you have a problem
now it seems that you look at these perversion from a social point of view "Hiding my perversions is a huge burden"
the real problems is that sins soils (literally) your soul and put distance between you and God, sins make God suffer because sinning you reject his sacrifice
STILL.. you are here, it means something in your conscience started to move, it means that God is still keeping a hand over your head, because he loves you and wants you to save your soul
sometimes people sin and sin, they feel that it is right, but they silence their conscience till indeed their conscience doesn't say anything anymore, they justify, rationalize their sins.. and it's the end for them
do not make this mistake..
God loves you and can make you pure as snow again (only pure things will enter Heaven and stay with him). so yeah you have reasons to be ashamed because perversion is bad but don't let this shame to stop you, don't let anything to stop you from joining God.. the Devil tries to trick you, he says that you have no hops, NO.. do not fall in desperation, if you repent, abandon these sins (and repair them when possible) everything will be alright.. this seems an impossible task right now, but don't worry because God, the saints, the entire Heavens are there to help you.
just ask this help.. God respects our will so do not think you will magically convert without effort and such.. you need to humiliate yourself, repent, ask with prayers to be worth of God, to have the strength to resist passions, to feel sorry for sins (this is important, sins are something horrible but we don't fully comprehend it usually).. and if you fail, ask again
do you have problem stopping to masturbate? stop with porn at least (it changes everything) proceed with steps, lower the frequency of this sins
if you put up a fight there is still hope, if you give up, if you start to justify yourself, it's the end.
God loves you and will never give up on you unless you give up about yourself first, I failed so many times but he always called me back
when you feel God's love for a second, just a second, you will understand that there is no true happiness in these sins that make us like beasts
if you are already interested in catholicism you can start with an easy and powerful prayer: the chaplet of Divine Mercy
talk with God, remember that he's there even to listen your weakness, share your burdens with him..
God's love you, we love you OP, don't lose hope, one day you will be pure like snow again
