Not sure your exact point ("...but do you seriously who wants..." if you mean you should wait, you shouldn't, either way don't masterbate?), but I am very glad my first sexual experiance was with myself. It's very empowering to realize that I don't need another to achieve that particular pleasure. It means on one level I won't ever need someone for that, which allows me to be much more discriminating with those I do choose to be intimate with since I usually am able to think with my brain and not... Besides, it's always good to know what you like and what you don't, what works for you and what does not. It's certainly no substitute for the real thing, but there are many worse things you could be doing in the world, giving yourself an organism hardly makes the list.
