Please give sex tips normies, I know you have them.
What exactly do you want to know?
This is pretty good advice. But don't make the same mistake as me when I was younger and put her needs above your own. Find a balance between your and her needs. And don't be afraid of bringing new stuff up that you want to try. Don't ask for permission either (unless it's something radically different than usually). Just go for it and see how she reacts. If sou're not sure ask if she likes it. Communication is key.
Keep it simple stupid. None of that alphabet shit. Just lick it like an ice cream cone for 5 minutes. If she hasn't cum by then she probably won't. Just give up and move onto sex.
Reverse cowgirl (less keen on this, but my gf likes it)
All are tried and tested; they're the most popular for a reason.
Completely up to you. I don't think it's expected of you, but it's also not exactly a subversive thing to do.
This is the most important tip, if you do this you need not worry about anything.
With your mouse, use your middle and index finger to left click. This is the fingering motion upside down. When you are presented with a vagina, insert your middle at first, then when it's in insert the index finger too. The palm of your hand should be resting above her clit, then begin. Play with her clit lightly at intervals too, if you get good at it, you'll know how to make her cum easy as fuck.
