SCREW THAT! When somethings wrong with your junk… you figure that crap out!
As it’s been said, some of this could actually have been fat as far as girth, length… I dunno how that would have worked. But as @Chris262 said, we talking flaccid or erect, that’ll tell you something right there. I’m gonna go with either your not exactly right for now as far as blood flow / vascular issue or your hormones are screwing up which is also pretty likely.
I can tell you as somebody that’s taken a healthy doses of testosterone, anabolics and other “fun” stuff that I didn’t medically need, that while your real size is set once you stop growing, you can effect how much of it you’re working with a lot more than you think you can. Most of it is hormone levels and blood flow.
If you’re in the states and don’t have insurance they’ll see you money or not. If you do have ins this kind of stuff is always covered. They don’t need to be keto sympathetic, you’re not there for a diet consultation.
If you want to do a little self doctoring, grab some horny goat weed and L-Citruline. Double the dose on both for a couple days and see if something changes. That’s basically poor mans Viagra. It’s NOT going to do what Viagra does but it’ll improve blood flow down there to a noticeable point, if you see a difference you’ll have a direction to troubleshoot in.
How much weight have you lost so far, how old are you and have you ever had your hormone levels checked in the past?
