I would differentiate between technique and skill. If you are below average then all sorts of tricks and specific techniques are available to help make up for that. (I know that some guys won’t like hearing that being small is something to "make up for".) If you are noticeably larger than your partner is used to then having a high level of skill in basic in-out is more important. You need to be spot on to not cause injury, which means you need to be able to read your partner.
Travesty, the guys have been giving you the absolute low down. No matter what your size, the most important thing is being a responsive partner. Once you get inside her head, you are golden.
For you, reading the advise being given, your response may well be: "OK, that is kinda obvious…now tell me the specific techniques!" The thing to keep in mind is that for easily 19 out of 20 guys the advise being given is NOT obvious. A vast majority of men will not only have a hard time understanding the advise you have been given, they will actually fight it! The "kinda obvious" stuff that the guys are sharing with you is advanced theory for most men. It is just that you are a natural, lol.
No joke: your mindset means that, limited experience and all, you will often be giving women better sex than her x-husband did in 8 years of marriage. And doing so the first time you make love to her. It is sad for women, but most guys absolutely suck in bed.
As for specifics? We have a number of advanced, postgraduate, sex techniques threads around. If nobody links to them in a few days I will dig some up.
