I am going about doing a mild stretching routine. 10ish minutes a day. Had a few questions as I still consider myself very new to all this.

Does one only gain from stretching if the BPFSL is LONGER than the BPEL? Right now my BPFSL is considerably shorter. About a half inch. It was worse before I started stretching however.

Will I not gain until the stretched length is longer than my erect length? Same logic applies to people who use extenders. Do you have to extend past your erect length to gain?

Also I have a fatter flaccid hang prior to stretching many days, and then after stretching it seems to thin out. Is this normal?
