A very creditable debut performance! But don't be so anxious. Let yourself go and and wank with more abandon. (You can always clean up afterwards!) If you do, I'm sure that you'll enjoy it greatly AND bring us ever greater joy in the future years. May I make a suggestion? Get yourself a co-operative friend, and you'll both grow to enjoy your mutual sexual activities so much more - and, of course, you'll delight the hearts of us, your viewers.
