Body pillows are basically double-long pillows. And your can get a range of rather explicit manga pillowcases for them. Some men apparently get rather, um, attached to them--up to and including marriage.
The options for male pillows are limited... and a bit more overt. I think I detect a gap in the market. No, wait, you can already get a male 'hug' pillow that comes with, um, an attachment.
