Well first of all this seems like a great product but it is amazingly hard to do. It was so hard to make and now my girlfriend is going to have a smaller version of myself. So Cool. I read the reviews and they were right how hard it was. You my as well by two of them because the first time is so hard tryin to get your member to stay hard and mix it all up. I couldnt even focus on my blowjob and when i got it all mixed I was not 100 percent ready. Oh well. So if you want one timing is everything and even when you have timing its pretty much impossible to keep it hard in that tube for over 90 seconds. If you buy one you my as well by two of them cuz you will mess up or be dissapointed that your cock is 1/2 the size.
