Sins, even mortal sins, do NOT need to be confessed in detail. In the case of mortal sins (grave matter, full knowledge, full consent), you need to say what the sin was and anything that would clarify its seriousness or reduce your culpability - such as "I had sex with someone not married to me - I am married and the other person was - married / of the same sex (whatever pertained). No need for further details. In the case of venial sins - something like “I accuse myself of losing patience a number of times with drivers who irritated me, lacked charity in my dealings with a colleague” etc. No detail.
The impression I am getting from your post is that you want to confess each and every venial sin in detail. This is absolutely not required and is time wasting. The priest does not need to know the details, only what your sins are and that you are contrite. If he needs further information, he will ask you.
Confessions need to be Clear, Concrete, Concise, and Contrite. You can always pray to the Lord about those sins that particularly bother you - any and all of them - but there are many others needing the priests absolution.
