Firstly, make sure you don’t come across as a stalker or an obsessive. Converse and see where it takes you. If there’s rapport you’ll both recognise it, if not it will fade. Just make sure if relationship is not reciprocated you don’t chase.

There is nothing like the direct approach...we are not mind readers!

Don't send a dic pic.

Secretly buy a secret home close to them.

Check out their profile, message them with a question or comment about one of their interests

I suspect it is someone you have already interacted with and may know a bit about them; start there.

Skype. Best have a face to face conversation before buying airline tickets.

Don't send nudes !

Sometimes it's more fun to have a secret crush than it is to maybe find out that they don't like you.

Have you made contact with them?

Exactly what Geoffrey51 said.

Oooh how exciting...I am going to be guessing all day

What outcome are you looking for? How deep have your conversations become? What's your intuition tell you from the tone of your conversations. Above all be honest. Ask, what's the worst thing that can happen, okay and what's the best thing that can happen from indicating your attraction. You don't have to be crass. Try subtlety.

Maybe start with a message, be honest about your attraction, no erotic comments, develop a friendship, then possibly email, photos and phone talks. If it grows then a personal meeting. Remember, if no one is ready to relocate and leave everything to start again with someone who's still a quasi stranger, then maybe it's more attractive just to leave it in your fantasies, it always works there.Good luck and leave updates!

I have that problem all the time. Good luck.

Okay, update. Holy shit... I just sent a message and actually hit send. We'll see!!! Fingers crossed.

Geographical distance is one thing. Emotional distance is another. Having a deep connection with someone and not having a dialog with them will kill the passion faster than not sharing a neighborhood.
