As humans, we are sinful by nature, and continue to sin even after we are saved.
(1John 3:9) Whoever has been born of God does not sin, for His seed remains in him; and he cannot sin, because he has been born of God.
Jesus died for all sin committed by all people, saved and unsaved, whether we did it just once, or every day.
Wrong! Salvation is only to those who obey Him!
(Heb 5:9) And having been perfected, He became the author of eternal salvation
to all who obey Him
Wrong! There is an advocate in Heaven but only to those who follow His Commandments.
(1John 2:1-3) ... if anyone sins, we have an Advocate with the Father, Jesus Christ the righteous. And He Himself is the propitiation for our sins, and not for ours only but also for the whole world. Now by this we know that we know Him,
if we keep His commandments.
Sexual sin is no different from other sins in God's eyes. I don't believe it is clear cut whether or not people who visit prostitutes or are homosexuals can or cannot be saved.
Again Wrong!
(1John 5:17) All unrighteousness is sin, and there is sin not [leading] to death.
There are sins that does not lead to death. Not all sins are same in God's eyes.
That is God's judgement to make, not ours.
Sorry mate, you are too late to say this. God had already judged:
Do you want a few judgments by God on the topic of homosexuals, adulterer and evil doers inspite of knowing God?
(Rom 1:20) they are without excuse,
(Rom 1:24) God also gave them up to uncleanness.
(Rom 1:26-27) ... God gave them up to vile passions.
(Rom 1:28) ... God gave them over to a debased mind, to do those things which are not fitting;
Read Romans 1:18-32 yourself and don't be misled by someone.
(1Cor 6:9-10) Do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived. Neither fornicators, nor idolaters, nor adulterers, nor homosexuals, nor sodomites, nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners will inherit the kingdom of God.
These are not 'our' judgment but God's and knowing God's judgment and still doing these abominable things are deserving death.
(Rom 1:32) ... knowing the righteous judgment of God, that those who practice such things are deserving of death ...
