I would like to ask a question on safe calls if I may.
Hypothetically speaking for now, because I wouldn't do it, but have had offers before to meet, and not just for a coffee.

I have been befriended by Doms, and have known them for more than a year, I know what they look like and am comfortable in talking with them.

I have been offered to meet for a play session, and while the offers are appealing and tempting, I cannot do so.

That got me to thinking about safe calls, I don't know anyone well enough to ask or feel comfortable in asking.
I can't use my friends, or my family, that would raise a lot of questions that I could not answer for them.
What does one do if there is no opportunity for a safe call? Is there any other methods that one can use?
