I have evidence that you are not a virgin - it's your admission that you were married for years. That is a presumption in law that you are not a virgin.
On this issue, your simple retort that "you are telling lies again" is a bare denial.
If there is already a presumption in law that you are not a virgin, the burden of proof is now on you to prove you are a virgin.
Your virginity test challenge does not prove you are a virgin. What you are attempting to achieve is to shift your burden of proof to others.
