New To Jelqing

I’m 19 and started jelqing just 2 days ago. I did some google search and heard that you aren’t suppose to jelq 100% hard because it can lead to damage. I was wondering if there is any good way to start soft while jelqing, since it just seems to get me harder.

Also I’m using vitamin E oil to jelq, anyone know if this is actually beneficial?

Thanks!
