A gerkin is not satisfying - but a shampoo bottle leads to bruising of the cervix. I’ll take “need to be satisfied in one of the myriad other ways” over “that ain’t fitting in here” any day.
So yes, size matters. Too big is worse than too small.
Now I feel bad. We were all newbies to the board at some point, racosun - and so far your netiquette has been very good. People here don’t mind newcomers making mistakes like posting in the wrong forum or not searching properly - it’s only people who are either trolling, “sock-puppeting” or just being jerks that aren’t well received. You did none of those things.
Size only matters in the extremes, IMO. Anything average to moderately-above or moderately-below and I can’t tell much of a difference (my experience). But if it’s exceptionally small, then, yeah, sorry - it likely ain’t gonna get the job done. And exceptionally large is just downright painful.
So, most guys are going to fit into that range where an inch either way just won’t be a big deal. (But, as the cliche goes, at that point it really is what you do with it!)
I think that one of the reasons that the topic keeps coming up is that it is a turn on for men to have women talk explicitly about sex. The size question is one of the few “not too creepy” ways to broach the subject.
I agree that proportion is important…unfortunately. I personally am smack-dab in the middle of the ‘average’ range, and I’d have no complaints except for the fact that I am 6’6" and proportioned so I look like a person of normal height until you see me standing next to someone. This makes my penis appear small on my body. Another inch and I’d look average, though I’d be bigger than most men.
