Thought I would share this tip, as it has worked with pretty much every girl I've had sex with.

Make sure shes laying down, and you're on top, missionary.
Hold her legs up, get them on your shoulders, put them in front of you and put them together, so her legs are in the air closed together.

Then keep fucking her, and this just seems to hit the spot EVERY TIME and they orgasm quite quickly.

Kinda like this: Deep Impact | SexInfo101.com

But hold her legs together!!

it will hit her gspot yes but if she can only cum off her clit it wont make her cum
if she only cums off her clit a good one i use is me ontop inside her obviously but like body to body and grind your hips on her, somtimes putting your hand under her ass helps too-- if you get the spot right you can grind her clit while your also getting off with your cock inside her.
same if she is ontop straddeling you , rather than having her banging up and down hold her hips and get her to lean right forward close to you and you can grind her clit that way too
these positions helps massively if you both have no pubes or you have a light stubble

There are different types of orgasms, it is quite possible to have an orgasm without any clitoral stimulation at all.

I didnt say you couldnt

Ahh, I misread that Refl3x sorry mate. I read that first line without the "if" so it read as though you were saying she could only do it that way.

if u do her from behind, thats called doggy style

If you do her in the ass and she has a rabbit at the same time or a vibe inside her pussy it feels fucking ace

My cocks that big she can suck me off whilst i bum her
