Thinks to self: "Count to ten, Will, and try and keep calm............."
Ok, let me try and be constructive here - so please take these comments as helpful and good natured.
First and foremost. Please, please, please use some punctuation. Fullstops alone would really help. It can be very hard trying to read a long sequence of words that are not broken up at all. If people can't be bothered to read to the end then they are unlikely to reply.
Secondly, the title looks rather brutal. I actually opened the message with a view to being pretty brutal in return but the text is not quite as bad as I had feared.
Having said that, a little more tact and delicacy wouldn't go amiss. I am not sure the size (even if it is genuine and, no, I don't want proof, thanks) is all that important. I am afraid that your post does rather read as if it is from a single guy - and a none-too-sophisticated one at that. I am sorry if that sounds harsh because it is not meant to be. I just suspect that this ad will not attract many replies as it stands.
I hope that helps and I am sorry if it comes across as condescending. No doubt someone will slap me for that very shortly.
Whether you do decide to change it or not, I wish you luck in finding what you're looking for.
