Hi there!
I have found most people respond to a good photo.
Yours are fine, but a bit distant. I would recommend adding a close up too.
Also I always like to hear what people are up to. Their hobbies, interests, or their work.
I mean: You live in Saudi Arabia! Thats pretty unusual so you could chat a bit about that..
And about the women who dont reply:
I would aslo recommend leaving out any private email addy, but seeing as you say you never sent any,.. I guess the women you wrote to are just incapable or rude,- so no loss there.
Just keep trying, it sounds like it was just the wrong women..
Good luck!
