Hi, and welcome to the forums!

My best advice to you would be to read! Just read and read and read, and bear in mind that a lot of the stories on here and other sites are fiction, or exageratred accounts of the truth. Then read summore.

Forums, stories, how to guides. Anything you can find.

Work out what turns you on, what limits you have, anything that's a complete definite hard no.

And then just keep reading.
