Huh? If your tongue & fingers gave her the orgasms and you were really good to her otherwise, why wouldn't she 'stay'? And who are these 'they'? I think you're being pessimistic ex-post-facto & intentionally scrambling information, man.
Um.. I don't have much more than 5.8" BPenis EnlargementL at the moment, and I don't have trouble at all stroking most womens' G-spots (which isn't too far in, might I add). You don't need much more unless you're trying to bump the AFE spot (or the cervix ; ).
I'm sorry, but with all due respect dude: that's about the stupidest thing I've heard. You need to prove you have a seven-incher to get a date??! Either you're a freak with no personality or anything worth liking besides a 'bulge', or you're terribly deluded, or you live in some other dimension where all women are nothing but crude, shallow size queens (talk about material for an alien flick).
In short, congrats for your gains if they are indeed real. But now that it's brought you confidence which is opening more doors for you, I hope you learn that women aren't the size-centric cock chasers you portray them as. I mean... give them some credit.
