My first was also my first wit a vibrator. I had a small vibrator, that I bought at a sex shop. It also helped that I was watching videos in a booth. Also too, I was becoming more confident that it was time for my female side to come out and my long ride home was talking to cross dresser. I was wet already. So when I slid that vibrator in...I literally blacked out because the feeling was so intense. I awoke to my heavy breathing and a long duration squirt I have been trying to have again. So my recommendation is that you need to be so sexually aroused that you need to be selfishly whorish with yourself. See as many videos that you know are going to make you want to cum. Lots of lube, and let your mind go on auto control. No worries, no guilt. This is your moment. Be true to yourself. You want it it. You are wanton, let it happen. And don't hold back. Don't even touch your penis. And trust me, you won't be unhappy with the mega orgasm that follows.
