I've had 3 specific situations that I can share with you:
1 - the first time my current girlfriend saw my erect penis (about 4 years ago), she let out a quiet, yet sincere, "wow". Now, as you can see from my stats, I'm not huge and, back then, I was even an inch shorter in length and a bit shorter in girth as well. The main reason for her reaction was (she told me later), that before we started dating, she would sometimes look at my crotch to try and figure out something from my bulge. Well, since I am a grower, she thought I would be much smaller
(by the way, I'm the only guy's she's ever been with, so I guess I'm kind of lucky that she has nothing to compare me with).
2 - after about a year or so of regular Penis Enlargement, I had to start buying XL condoms. It was really fun to catch the cashier at the pharmacy sneak a peek at my crotch while I was paying
3 - I've mentioned this before in another thread. I was once wandering around with my girl in a shopping mall, wearing light cotton grey tracksuit pants (and boxer shorts), and she kept rubbing her body against me on purpose. (by the way, my girl has the "Midas" touch... it's almost like every time she touches me, anywhere, I start getting aroused
). So, eventually, it had to happen... I was sporting a semi-boner, which I really couldn't hide, when suddenly a couple of girls pass by us and one of them couldn't keep her eyes off my bulge.
One other thing I am sure of is that, ever since I started getting results, I have a bigger bulge, and it gets noticed much more often while in public.
