yes...learn from my experience! I gave out my number to two different guys early in my online days last year. Both texted me really inappropriate things and one offered to send a pic of his morning wood. INappropriate!!!
Now I don't give the number unless/until we agree on meeting. Then I exchange numbers in case one of us has to get in touch w/the other at the last minute for any reason (running late, fell in a well, you know, the usual)
