I ended up deciding to wait and find out what others would say before I respond, I hope you all don't mind. I suppose you could all consider this part of my phallo research.
CMD042414, seems like we're on a similar wavelength. Like I mentioned in my original post, I don't understand why someone would want a small dick should they get a phallo.
I can understand wanting a phallo that fits one's body size, but why not go a little longer if you can? A 7"/18cm cock isn't too much more than a 6"/15cm one, and for my mental well-being, that extra length would make me a very happy man.
I AM seriously considering a meta in the future, but IF I decide to go all the way and get a phallo, I want it to be a decent length. I have no problems being semi-erect all the time, as long as its the length I want. But, I also want to be a normal girth. If its too big around in girth for my partner to enjoy, then there goes a decent part of why I'd even want a phallo in the first place. No pop-can girth for me, nothankyouverymuch!
Nice fitting clothes is also something I will have to take into consideration. I tend to wear skinny jeans, and my 4.5" packer gives me a decent bulge. If I have to have a cock that will remain the same size limp or erect, I will err on the side of slightly longer than average, even if its only an inch/2.5cm longer than normal. I definitely don't want a baseball bat in my pants, but I also don't want something that is so small that I'd need a magnifying glass to find it.
If I have to tuck or whatever longer guys do to fit into tight pants, then I suppose I'll just have to learn what it is they do.
I'm not vain, I just want to be a respectable size, both for my mental well-being, and to be able to please my partner as well. At 5'7&1/3rd "/171cm, I feel that 7"/18cm would be a nice size for someone of my height and build.
I have both a 6"/15cm strap-on and a 8"/20.5cm one, and the 6 inch one seems to be too short for me when I look into my full-length mirror, while the 8 inch one is too long. So it seems to me that my Goldilocks zone is 7 inches.
I also DO know how to please my partner, so having a cock that I'm not only proud of, but know how to use along with foreplay and even afterplay would just enhance our fun.
And no, I'm also not into women. My partner is a genderfluid transman. A nice length and dick of a normal girth would only enhance our sex life.
Everyone's responses has definitely given me plenty to think about.
