Well, thanks to Cialis and these NOW Men's Virility supplements I've been taking I can have a real hanging flaccid of almost 6" (5.5" right now) during the day. I'm a big guy, with huge legs, and even I can still show off a pretty "sick" flaccid. I notice that quite a few girls in my Accounting class stare. I have been wearing tighter pants (I'm used to baggy ones that would sag) and have noticed that my penis tends to start really jutting out to a 45 degree angle across my thigh sometimes.
This seems to REALLY get women going. They love that mystery behind the pants, and I bet they really get off on seeing your coronal ridge outlined. However, I notice that guys really crotch watch as well, blantantly. The other day I was at a country club's pool, with swim wear that is quite light material and really is "form fitting." Anyway, I was on my high-point with Cialis, plus I smoked a bowl of some extremely high quality Satori (sativa medical plant). Cialis + weed calls for an unreal flaccid, as I was really just vibing and so relaxed, enjoying the atmosphere. I had no less than a 6" flaccid the whole time, even sometimes walking around with an almost-wooded 7" "flaccid." When we were about to leave I started to get an uncontrollable erection and I was about 1/4 hard leaving. A few guys near the front saw me. A black guy that saw me had this priceless expression, he had this "woah" look on his face and his eyes almost shot out of his head. I would've done the same thing, I'm pretty modest about seeing shit like that and I usually turn away when I see someone's bulge. Then as I was leaving to the parking lot I thought I was clear, yet a good looking lifeguard chick was leaving in her car and was letting me pass infront of her. I let her take a long look at my 1/4 hard cock swinging in my swim shorts, which were "hugging" my penis. Wow that was a fun day.
The key to showing a bulge is the fabric and size of clothes you're wearing. In the normal, looser clothes that I wear I still show a bulge (5" flaccid baseline), although it looks like a 2" flaccid because my pants are sagging down my waste some, so you don't get the full view.
As far as scrotal stretch goes, I think having lower-hangers would help more. I have a pretty good low hang most of the day. I find that when my balls are tight that I don't have as good of a bulge. Plus, it's attractive when everytime you put your thighs forward to take a step and you hear a "flop" sound from your big dick and balls slapping against it.
