Unfortunately, massage parlors are often targeted as business that engage in prostitution.  You may unknowingly agree to perform or receive a massage at a massage parlor  only later to be charged with solicitation.  Vice offices will often take over a massage parlor and entice and encourage customers to agree to acts of prostitution.  Remember, paying for a massage is paying for a massage.  You have to knowingly pay for sex to be convicted of solicitation.   Don't plead guilty or no contest without calling an attorney first.
