Umm, I guess this is really off topic, but I believe they do make "artificial devices" that "squirt." You should check around some adult shops. Maybe Fetishes Boutique, on Fifth Street, a couple of blocks south of South Street.
I'm sure you're very fortunate to have found a lady who enjoys your fetish as much as you do. You might think it would be easy to find another gay guy to share it with, but I'm here to tell you, it ain't so!JSN2SPNDX[/i]
