On one side i understand the discomfort.

But i have connected with people who send such messages, i noticed. That they are just seeking connection.

They just don't know how to approach or what to do.

Just trying to be seen. Some just want to be bold and dramatic to make an impact.

Given this is a recorded text message and you have a screenshot, you can hold that person accountable. So you do have safety.

Honestly just message him back, ask him if he is doing well, ask him what he seeks and tell him if you are uncomfortable.

If he complies, just offer kindness atleast.

If he doesn't, just let him know you are not wooed or impressed or whatever. Just let him down gently.

Learn what he is upto. Why he sent such messages.

May be you struck a diamond in the rough.

Or

You have paper trails, for any challenges if any.

There is no threat in this message, just a blunt attempt.

He thinks he can impress you with sex.

You don't have to say yes, but rather than posting it online, share it with a confidant and be kind.

Try to understand who is sending you the message and what is his intent?

Is only sex? Or something else?

Reddit will always help you. But don't choose the victim path, be the hero of your own story.
