Happy birthday, MR INSALL!
As for your 4.5 inch penis, I can't tell you not to wish it weren't bigger, because I've always wished that mine were bigger, but I've got news for you: Just about every guy wishes he were bigger. 4-5 inch guys may wish they were 6 or 7 inches. 7 inch guys wish they had 8. 8 inch guys wish they had 10. Even the rare guy with 10 inches hears about someone with 11 and wishes that he just had one more inch. Few of us are truly 100% happy with what we've got. It's not just about dicks, either. We all want something more than what we've got. A better job, a bigger house, a sportier car. I guess it's just human nature. You may not be able to stop yourself from wishing it, but you can decide not to waste time and energy worrying about something you can't change.
This site really distorts your perspective. Before I came here, I perceived myself as a bit bigger than average (although I still wanted to be bigger). Since I've been a member here, I am less satisfied with my dick, and I now see myself as smaller than average.
You're 19. You're probably done growing, but maybe not. Either your dick will grow a bit bigger or it won't. Accept that you don't know and accept that it's not really something you have any control over, and start enjoying the body you've got.
For what it's worth, if I could choose between a bigger dick and having a cute face/body, I'd choose the face/body. Few people in the world are ever going to see or touch your dick, but lots of people will be drawn to you--or not--because of what they see on a daily basis, not what they see in the bedroom.
I can tell you that I would never reject a guy as cute as you because of his dick size, especially if he's got the personality to match. Most of the guys I've been with have been about 4-5 inches long, and I've never felt dissatified with that. I love looking at big dicks, but I'm rather intimidated by them. I wouldn't know what to do with one. (I've never been with a really big guy.) When it comes to actually having sex, I prefer small-average sized ones, especially for oral sex. I love it when I can fit a guys whole dick in my mouth, but I have a sensitive gag reflex and I'm not much of a deep-throat artist, so I have trouble going down on bigger guys.
As for anal sex...well, that's not my area of expertise--many gay men rarely or never have anal sex (including almost every guy I've been with), so it may never be an issue for you. Some guys like to get fucked once in a while, but don't want it all that often. Such guys may prefer to be fucked by a small-average sized dick.
You may have a problem if you hook up with a power bottom. You may discover that you're sexually incompatible. If that happens, you can go your separate ways, or you can just be friends. If you find yourself in love with a power bottom, then you may have to find some creative ways to enhance both his pleasure and yours, such as using toys, or even fisting.
One of the hottest porn videos I ever saw featured a big dicked guy paired up with a little dicked guy. Usually in that scenario the big dicked guy is the top and the little dicked guy is the bottom, but in this vid it was the other way around. The little dicked guy was obviously a very talented top, fucking the big dicked guy hard and fast. It's hard to describe, but the little top seemed to have a certain rhythm to his fucking, and it seemed to be an effective technique because the big dicked guy was writhing in pleasure until the little guy fucked the cum right out of him.
As for penis enlargement, I don't know much about it, but I'm fairly sure that it were were truly a safe and effective technique for penis enlargement, we would know about it. Although I've always wished that nature made me bigger, she didn't, and I accept that. My penis has always been a great source of pleasure for me and I've never had any complaints, so I'm not going to risk damaging it to gain a little size. I don't have the right to tell you to stay away from PE, especially since I know very little about it, but if you do consider it, please do some research and proceed with great caution. Don't be persuaded by other people distorted self-image and wishful thinking.
Have a great birthday!
