I'll liquidate my share portfolio and buy the most state-of-the-art real doll in existence before I let a fatty even imagine what I look like naked.  If the option of banging a thin girl is gone I still have the options of: becoming celibate with the assistance of high end sex toys; killing myself; rubbing my dick on a rock until I reach orgasm; or developing a penis-enlargement solution that works and then fucking my own ass. All of those are vastly preferable to touching a fatty.
