After Years I've Made Progress But Have A Question

I’ve gained 1.5 inches length, .25 girth jelqing on and off for 3 years. I don’t have sex often but did several times during this journey and noticed something I want to ask about:

Has anyone else noticed that now that their dick is bigger they don’t slip out of vaginas as easily and therefore sex is easier / goes more fluidly?

Currently I’m 6.8 inches by 4.8 inches

I was reading more recently and realized that I’ve been jelqing wrong all this time due to my dick bring sensitive and getting injured easily, I’m thinking that doing my exercises better from now on will lead to faster gains, my goal is 8.5 x 5.25 inches.

Can anyone give me a reason why I shouldn’t keep increasing my size? Will I start to be too big for some ladies or does added length continue to improve the quality of sex? Is there a realistic upper limit on that for most vaginas like 7 inches? I read that my current size is ideal among a couple of surveys of women but I find that the bigger my dick gets the better my self esteem becomes so I’m kind of addicted to PE now.

I’ve also noticed I cum far easier than I used to and read about about that, seems common and I think I know what to do about it.

Something else I’ve noticed is that as my penis has grown the shape of the glands has changed, and I like the new shape, it seems more defined.

Before I started this journey the dicks in porn looked huge, now some of them look like mine.

For example: before too much longer my dick will look just like Mark Rockwell’s, which is an awesome feeling for me.

The size of your dick has nothing to do with the quality of sex.

There’s what most the ladies say, yet they continue to be impressed by large dicks.. And since female sexuality has everything to do with psychology.

Also, that is probably false: a micro penis won’t satisfy while one too big will hurt her. But for guys in my range it might not matter too much, you’re correct in that sense

And I’ve read several stories on here regarding both positive and negative female reactions to PE.

And most women I’ve spoken with about this say more girth = faster orgasms for her up until the point where it just starts to stretch her out painfully.

Another thing I noticed is that I went from being a grower to bring a shower.

Let me also say that despite years of repeatedly jelqing with too hard a grip I still wake up most mornings with a rock hard erection.. The human body has an amazing capacity for repair.
