So wrong in so many ways. Sounds harmless and all, but he is seriously deluded. You probably already are in a relationship (D/s or not, but most likely it is), and why would you be interested in a free relationship with some random guy messaging you via a pay for sex site?
Offering submissive services I can only imagine the kind of bs men tell/ask you!
I was tempted to write him a novel explaining that's not how any relationships are founded, especially d/s ones, but instead settled on telling him I am already in a happy and commited d/s relationship with my partner. Unsurprisingly I never heard back.

Most clients are sensible with the sub requests but some of them I want to hit with a metal chair.
Todays gem:
Hi, where are you based?
I am near xx.
Are you available after 2pm for 15 mins?
Yes, I can book you in for 2.15?
How much and what's your address?
(While eye rolling and no longer believing he was genuine.) My postcode is xx, it is xx.
Never heard back until 2.40, informing me sorry he only just finished work.
Not a problem, between your first and last text I managed to see 3 regs - one who I gave your time slot.
