Hey Cosmology,
I’m also a late bloomer like you. But I can tell you that late bloomers do in fact bloom. When I was your age I was at about 5.5” long or less (BPEL) I don’t know what my girth was, but I’m guessing it was somewhere between 4.5” to 4.8”.
I had no idea what the average dick size was, but I did suspect that I may be small. All I knew for sure is that I had a girlfriend that craved my dick. I used to tell her all the time what I was going to do to her with it - on the phone, text message, letters, every chance I got. We were young and horny. She would love to play with it every chance she got. I could make her cum anyway I wanted, even just by dry humping her. She thought my dick was awesome, because she thought I was awesome.
I hope you see what I’m getting at. I’m talking about the psychology of sexual pleasure. There is so much more that goes into pleasing a woman sexually than just your dick size. And this is the best thing you can know from now.
By the time I hit 21, it had grown to about 6” all on it’s own without my intervention. I didn’t know much about PE at that time, except that PE couldn’t really work (how wrong I was).
Some of the advice given in this thread is really good. They are right about confidence being more important than anything else. So, work at PE, but don’t forget to work on your confidence also. You will find some guys on this forum with 7, 8, or 9 inch dicks who still feel insecure. So quash you’re insecurities from now, getting a bigger unit won’t make it go away. You will have it as long as you measure your worth by your dick size.
Now on to practical matters:
You’ve come to the right place to grow your member. But when you say you are “depressed and desperate” it worries me, because I’m afraid you might overdo it. Take the advice given in this thread and start the linear routine and work your way up over a few months to the newbie routine. You’ll find these in the PE manual.
Remember PE is a marathon, not a sprint. And more often than not, bad things happen to those who try to turn it into a sprint.
Now, as pointed out previously, you didn’t say if those 5” is BPEL or NBPEL. If you don’t know what those mean, then you need to do some reading in the PE manual. Do the reading, learn the lingo, and interact with the members and you’ll get plenty of help, support, and motivation from the Thunder’s community.
PS: Don’t even get me started on the facial hair. I still can’t grow a proper beard. I can grow a pretty good moustache now though, finally. Anyway, the ladies will love your youthful face. It’s all a matter of your own perspective.
