Is it possible to deal with these feelings that go beyond friendship and reach the desire for sexual practice with a friend, which the questioner describes as sexual perversion, while preserving the relationship between the two friends?

Exaggeration in loving people is blameworthy, and if it leads to the abomination of sodomy, it is forbidden and considered among the major sins. It is obligatory to stay away from this young man, for a friendship not based on piety has dire consequences. This is from the embellishment of Satan, who corrupts religion and morals, and this affection will turn into enmity on the Day of Resurrection, except for the pious. We advise you to repent, stay away from associating with bad company, choose righteous companionship, and attach your heart to mosques and gatherings of knowledge and remembrance. You should also increase in good deeds and occupy your free time with what is beneficial, and frequently supplicate and seek help from Allah.
