bust-n, welcome to the forum.
First I have to point out that we encourage proper grammer and punctuation here and not chat speak like “idk” or “ur”.
I also like to recommend that new members take some time to search the forum and do some reading. Most of your initial questions can be answered without posting, simply by reading the basic information here.
To answer your question, there are lots of variations on the “regular” jelk, and what you describe sounds like a common practice. A hand at the head can help to build pressure during the jelk.
Finally, if you are new to PE, I recommend that you read and follow the newbie routine, before trying ( or inventing), other exercises.
