not that im an expert....but we have lots of passion parties in texas. and the chicks that normally host them....have vehicle stickers and placards for advertising. I am not so sure that you will be arrested because you have 10 dildos or a box of condoms.
no different from me riding around with 10 shotguns in my backseat. as stated in prior statements, you do have the right to refuse a car search. they do these at random check points especially when traveling to catch traffickers.... Can we say probable cause? Sex toys is definitely not what they are looking for. best case is your going to raise an eyebrow about why you carry so many.... and your excuse should be ....i host passion parties.
