I agree with you, koooky, but sometimes it "just happens." For instance, I'm in a similar situation as RichSteele but then I agree with Kong and don't let it get to me... much.
I'm around 6.5-in NBP (7.25 BP last I checked, been out of Penis Enlargement awhile and trying to get started again), and occasionally when I get one of those diamond hard-ons we all crave, I can hurt my current SO when I go too deep (she's about 5'7" or 5'8", so not small by any means and has also had 3 kids, but she's still fairly tight and apparently not too deep -- I previously dated a girl who was only about 5'3" and rarely would I bottom out in her, but it is fairly regular with my current gf).
Anywho, she's complained of soreness from me going too deep on a few occasions so we started discussing it as I didn't want to be hurting her, so I asked some questions about what I needed to do different as I'm not interested in leaving any part of my soldier "out in the cold" if you know what I mean. One thing led to another and we're talking in almost technical terms about her inner workings and my penis when she mentions how her ex-husband frequently made her hurt this same way and that doggy style especially was out of the question as he always seemed to go too deep. It wasn't until this point that some e-vile demon in my head decided to play mind games with me and whisper, "You only go too deep 'occasionally' and only when you're sporting a raging boner... but this guy used to do it 'all the time'. Don't you feel wonderful now? Uh hahahahaaa!" Motherf....
But I always try to remember the other things she's said about him to offset this. Such as how when we first met we were having a ridiculous amount of sex and I usually last a good hour or more and she always referred to him (and most of her other lovers) as "the 3-minute Man". Or how he rarely was willing to try non-missionary positions, and he insisted the lights be off; after years of marriage, they had never once had sex during the daytime. And how she could only have an orgasm if she was on top, that I was the first lover she'd had who could make her orgasm in basically any position. Or how the sex was so infrequent after over 10 years of them being together that in the first 9 months or so we were together, we'd had sex more than she had the entire time she'd known him (and she loves sex).
So, you have to focus on the positives; I would assume in your case, Rich, that they far outweigh the negatives -- she's basically told you as much. While you can use the negatives to fuel your desire for Penis Enlargement, I've always been of the opinion that you should be doing it for yourself and for your own reasons. My gf has told me many times I'm the "perfect size" for her as I fill her up but not to the extent that I hurt her, but I'm getting back into Penis Enlargement for my own reasons which are the same as when I started before I even knew her: *I* don't feel I'm big enough and want to be slightly bigger -- if it looks like this is going to be long-term, then I will make sure to stop if hurting her becomes regular, of course, but for the time being, especially in the girth department (which I think she'd enjoy, actually), I'm going to keep Penis Enlargementing. And every time that annoying little voice pops into my head, I just shut it up by thinking, "Yeah, but he sucked in bed and I can make her cum almost at will. Anything else you want to talk about?" Chirp. Chirp. Chirp.
