My best method costs a bit of money but it is well worth it, believe me !
I bought an Aqua Massager which I believe you can buy on e-bay for about £20.
I first like to read a few stories on Solo Touch to get me in the mood then I love showers to I take my Aqua and connect it to the shower hose and turn it onto a slow setting at first and circle my pussy lips. The water flowing around my clit really gets me going, I sometimes just do this as it is really intense. I have tried using warm water and then ice but that is a bit too much like hard work. After I have done that for about five minutes I then turn the shower off and just go for it by putting the shaft deep into me and then I am away.
I recommend that you make sure that there is no one in the house when you do this as I make me screem.
