Final caution.  I use to obsess about my average size cock.  It drove people away, not my size, my obsession with it.  If they say they are okay with it, take them at face value.  I remember one FWB I had who was a good 8" and a total slut and loved to flip flop.  He got a bf for a few months, and we he came back on the market..he came right to my dick to get fucked.  He said he loved the size and he could not get enough of it.  I don't know why always helped my confidence that this total slut with choice of dicks came running to mine.

Absolutely every single guy I know with a massive dick – and I know a couple with insanely huge schlongs -- complains that it gets them less sex, not more. Most people aren't willing to take too big a cock, which results in these guys usually either having to focus solely on oral and manual, or if they really want to do anal sex, they have to bottom. Which is cool with some people, but not for everyone.

Big dicks are, by and large, one of those things that a lot of guys who don't really have a lot of experience think it would be great to have or to be with...until they do. It's not the case with everyone, and I certainly wouldn't assume every single person's experience in life, but speaking from my own, that's the case.

Choose someone to have sex with that knows what he's doing and can have fun, not by how big his dick is. They grow and shrink depending on a lot of factors anyway, so it's hard to say any single size any single penis has. You're better off not overlooking someone because you think their dick is small, especially since a lot of people have a hilariously delusional view of what even makes for average penis size.

The porn dick size is for the most part, well above average. And while it;s nice to look at- it isn't really the easiest thing to handle. 
So to answer the question as many others have- yes I would definitely have sex with a guy with a small dick. 

This is refreshing to hear because I've often thought I'm way too small for anyone to really enjoy my dick, which is 5.5 - 6 (on good days), even though all the tops I've been with have only ever been 6.5 inches max. I've always found between 5 - 6.5 to be really pleasurable, but that's also the only sizes I've had.

It's strange that I'm so insecure when my dick isn't much smaller than the average, I think ironically enough, porn has a lot to do with this. We always see these really big men and we assume it's the standard and we can even get down on ourselves and think we're not desired because we're not hung like porn stars, but this is just bad thinking. It's good to know so many of the forum members and other men realize and acknowledge this, makes me feel less insecure about my size and I'm sure others who are on the smaller end reading this will feel the same.

To answer the question though, as a vers/bottom, yes absolutely I would have sex with a dick that's 4.5 inches, most of the dicks I've had sex with haven't been much bigger and I've always orgasmed  It's the person attached to the dick that's the most important factor.

So I have a dick that is basically small 4.5 in erect to be spcific and would you have sex with a guy that has the same size dick as me or do you have a limit?

Judging from your username, I can assume that you're Asian. Since I myself is Asian, I can tell you that your size is undoubtedly normal for our race.  

Size doesn't really matter tho. What matters the most is how BIG your personality, character, and more importantly heart is. And that appeals more to me too. Although it would be a plus to have one, I don't care about the size of my lover's dick. It's his heart that wins me over, not his dicks.

@rlynnc:

To me it's more about who I have a connection to.  If I have strong emotions for a man, what is between his legs is perfect for me.

THIS!

Beside, some guys can still look really hot eventhough he has average sized dick. Sean Cody's Brandon is a good example. He's popular, eventhough he has what they call 'a husband-size dick' when compared to other models. Many power-bottoms on the site are dying to be topped by him.
