I’m a Fleshlight newbie, what is the first one I should get?

Start with an Original Pink Lady, it’s a good introduction to what Fleshlights are like. The 3-4-2 deal allows you to pick 3 Fleshlights for the price of 2. After trying some of the original Fleshlights, read up on reviews and decide what your next step will be. There are plenty of other textured Fleshlights to try, and are highly rated by veteran.
