Getting started

I’m brand new to PE and haven’t tried anything yet. Been watching some of BD’s YT vids and searching this forum a bit but It’s a lot to take in. Wondering what is recommended to start out with for someone trying to focus on girth but would like to add a bit of length too. My current sizes are, BPEL =5 1/2” MSEG = 4 1/2” and BPFSL varies a TON like anywhere from 2 1/2” - 5”. I think one of my main issues is my EQ, never feels like I have a solid hard on. I’d also like to improve my soft size, a lot of times it’d just shriveled up any tiny, not sure why that is. Anyway, looking for a beginner plan, would love to just pump but sounds like it would be smart to add some stretching or something else as well
