No-one is mocking you, but everyone thinks that you have asked a question that is impossible to answer. It is like asking "Should I buy this dress?" without describing it - it could be any dress, in any colour, any size, any style.
You have told us nothing anything about this man, how long you have known him, your previous relationship with him, your age and his, whether he has any authority over you (teacher? neighbour? stepfather? doctor?) or whether you are both young teenagers or old codgers in a care home. His identity is perfectly safe! So is yours.
You could be a worried child who has been sexually abused - in which case you should be contacting childline (0800 1111)
You could be a young adult who has met someone your own age who fancies you - in which case, we wish you well but remind you to Be Careful.
You could be setting us a puzzle to tease - if that is so, I would vote for him being a doctor or dentist who is checking on your teeth or your neck glands.
You could just be someone winding us up to see what replies you get - in which case, you have your replies, now get lost!
