I see thin dildos in porn all the time. Granted, there are plenty of scenes with big ones, but the only thing worse than seeing a pornstar with a small dick is watching a woman masturbating with a thin little dildo. I would assume pornstars are a little more loose than most other women (some assumption there, huh?) so they'd prefer a nice fat dildo, but I still see thin little wimpy dildos in porns all the time.
Why do think that is? Do they actually choose to use these?
