Venial sins do not require direct confession to a priest to restore yourself to proper communion with Christ’s body, and I think the point is that, while venial sins are harmful, they don’t break that communion. (I don’t mean excommunication, here. Communion might not be the best word). Sincere repentence and proper disposition in receiving the Eucharist heal whatever is damaged through venial sins.
If I might state my own opinion, and it isn’t reflective of the attitudes on these forums but of what I’ve seen “out there”, is that some people take the mortal vs. venial issue a little too legalistically and venial sins are just shrugged off. I don’t claim I’m perfect, mind, but theologically it seems important to me to remember that all sin is harmful to our relationship with God, including minor ones, even if minor ones don’t count as a full out break or rejection.
Going to regular confession to stay on top of that relationship with God and his Church, even for venial sins, can be a good thing, and help one in striving to be perfect. You just want to be careful of taking that too far into scrupulosity.
