Girth, by stretching?

I’ve been doing a stretch routine only for the last 3 weeks. My bpfs went up exactly 1/2”. My bpel went up a 1/4”. My girth also went up to 5 1/2 from 5. Is this normal?

My bpfsl also increased by roughly that amount, in a month (5/8 inches). I was not lucky enough to get any girth though. I only do manual stretches, including DLD blasters. Do you do any jelqs?

Stretching over long periods of time is supposed to increase length and girth (the method of action of stretchers like penimaster). So, I guess, if you are stretching for long enough, you should be getting added girth.
