Sin Well I guess we all know my feelings about these things... but I think getting to know your own body is really important. It's a beautiful experience and we should all indulge from time to time.
Staying chaste for a future partner is a completely separate issue in my opinion. You should know how to work with them and guide them, otherwise that 'first time' that you're all waiting for is going to be a pretty awkward, anxiety-ridden, painful experience.
I can't determine whether your being here is a blessing or a curse for me. On the blessing side your postings are a breath of fresh air, on the other hand I'm tempted to come back so I can read them.
