Let's me throw some advise you why from an OG.
First off, do a 90 beginner routine for conditioning purposes (JP's I do recommend). This will give you the fundamentals of PE as well as getting your penis used to that kind of resistance, and your brain as well as to knowing after a while that PE is not for stimulation but physical modification of the penis (so, persistence is your friend). Read JP's instructions carefully which you can find in the first page of the Beginner's Forum of this site.
Don't be discouraged if you don't see any gains but just better EQ for a while. The fact is you don't really know the handicaps of your penis for gains. It takes time to know that and also know what you need to work on to overcome that as well. Mine is my tunica.
Be aware of your PI (physiological indicators). If you are not overdoing an exercise, you should not run into any problems with that for the time being.
Also research all you can about PE with the pros and the cons educating yourself in it.
I will not say anymore because it would be outside the realm of a novice PE'r. After three months, you will have some idea of trouble area (handicaps) which you can post on then.
Lastly, be safe else instead of gaining a bigger penis you will gain injuries.
