I'm looking for a female chastity belt with only one dildo for the vagina but can't seem to find anything. Everything I have seen has a vagina and anus one too.
Could you get one with neither plug nor dildo and then just stick a dildo in before whacking the device on?
this one http://www.lovehoney.co.uk/product.cfm?p=15753 says it has removable dildo's so you don't have to have the anal one if you don't want to
