if you want to see the full sex scene in GTA SA, go find
"hotcoffee" mod.
GTA SA without that mod, you can date girls(during certain time of
the game) and then she invite you into her house for "coffee", if
you choose yes, you see the house shaking up and down for a while,
then you come out.
If "hotcoffee" mode is installed, you can date them anytime in the
game. And when she invite you in and choose yes, go get to play
some mini game. During the mini game, you can see sex scene.
