Yes I confess my sins and ask forgiveness! Every single day. There are two types of forgiveness seen in the Bible.
The first deals with our salvation. This is the forgiveness that Jesus bought us at the cross. Once we are given this, we are saved from God's wrath and there will be no condemnation for us on Judgement Day. This is what is meant by "there is no condemnation in Jesus Christ." We have full confidence that we will not be sent to hell for our sins. We are not condemned.
The second type is relational. Now that we've become God's children, we confess our sins to keep our relationship with God from being broken. God won't take away our salvation, but we can lose a close relationship with God. You see David, who was already a saved believer, doing this multiple times in the Psalms. (
Ps. 6; 32; 38; 51; 102; 130; 143)
Look at what David wrote after staying silent about his affair with Bathsheeba for 1 year. He wrote this
after God had told him he was already forgiven in 2nd Samuel : "When I kept silent about my sin, my body wasted away through my groaning all day long. For day and night Your hand was heavy upon me; my vitality was drained away as with the fever heat of summer…I acknowledged my sin to You, and my iniquity I did not hide; I said, "I will confess my sin to the Lord"; and You forgave the guilt of my sin"
In Revelation, we see Jesus commanding already saved believers, of whom He has many good things to say about, to repent.
"To the angel of the church of Ephesus write,
These things says He who holds the seven stars in His right hand, who walks in the midst of the seven golden lampstands: 2 “I know your works, your labor, your patience, and that you cannot bear those who are evil. And you have tested those who say they are apostles and are not, and have found them liars; 3 and you have persevered and have patience, and have labored for My name’s sake and have not become weary. 4 Nevertheless I have
this against you, that you have left your first love. 5
Remember therefore from where you have fallen; repent and do the first works, or else I will come to you quickly and remove your lampstand from its place—unless you repent. "
Again:
"And to the angel of the church in Pergamos write,
‘These things says He who has the sharp two-edged sword: 13 “I know your works, and where you dwell, where Satan’s throne
is. And you hold fast to My name, and did not deny My faith even in the days in which Antipas
was My faithful martyr, who was killed among you, where Satan dwells. 14 But I have a few things against you, because you have there those who hold the doctrine of Balaam, who taught Balak to put a stumbling block before the children of Israel, to eat things sacrificed to idols, and to commit sexual immorality. 15 Thus you also have those who hold the doctrine of the Nicolaitans, which thing I hate. 16
Repent, or else I will come to you quickly and will fight against them with the sword of My mouth."
Again:
"‘These things says He who has the seven Spirits of God and the seven stars: “I know your works, that you have a name that you are alive, but you are dead. 2 Be watchful, and strengthen the things which remain, that are ready to die, for I have not found your works perfect before God. 3
Remember therefore how you have received and heard; hold fast and repent. Therefore if you will not watch, I will come upon you as a thief, and you will not know what hour I will come upon you."
Again:
"As many as I love, I rebuke and chasten.
Therefore be zealous and repent."

Another example would be Paul's letter to the Corinthian church in chapter 11. Here, Paul is discussing believers who are taking communion without properly examining themselves. (Further in the chapter Paul explains their sin in more detail - not considering others at their communion meal.) Through Paul addressing this issue in the church,
we see that believing Christians can indeed be judged for sin they refuse to face i.e. confess.
And Paul tells us why.
Each one must examine himself before he eats of the bread and drinks of the cup. For anyone who eats and drinks without recognizing the body eats and drinks judgment on himself. That is why many among you are weak and sick, and a number of you have fallen asleep.
These believers are being judged. Why? Is it because He's pouring His wrath on them? No! It's because God loves them and is treating them like children! God expects these believers to examine their walks with Him. If they won't do it, God will.
Now if we judged ourselves properly, we would not come under judgment.
But when we are judged by the Lord, we are being disciplined so that we will not be condemned with the world.
Here we see God's faithfulness. He promised us that we would not be condemned if we believe in Jesus Christ. He will keep that promise, even if it means saving us from ourselves and taking us home early.
In fact, if you are not being disciplined for your sin after beconing a believer, something is very wrong. Hebrews 12 covers that topic
I hope that helps a little, friend! As a young Christian (3 years :/) I don't know much yet. Scripture seems to explain itself pretty well though haha.
