Hi ju5taman, welcome to Thunder’s Place.
I like to have at least a two hour buffer between my PE sessions and "releasing". I don’t think it’s detrimental to your gains though, I’m just superstitious like that.

Yes, quite a few actually. Below is a link that details most of them. However, I must warn you that anything more than moderate jelqing when you first start PE can be dangerous. Start out slow for awhile to get your dick prepped to being worked out before trying any of the advanced girth exercises.
Here’s the link: Girth Routines
One other thing, in case you haven’t already, please read the forum guidelines when you get a chance. There’s a lot of helpful information in there that will help you get along here.
