It goes both ways. I am 57 and get a lot of interest from guys in their 20s and 30s who don't care how old I am and actually think I must be a lot younger than my age. Personally, I don't care how old or young someone is, if they are legal and able and willing and consensual, then have fun! And for the record, no guys that we have ever hooked up with have ever had any complaints due to my age
And on the other topic, yes, I constantly get messages from BC and Alberta and the Maritimes, (even other countries) even though I live in Ontario. Even most of the people in Ontario are too far away for us to consider. It can definitely be disappointing to start talking to someone, feel good about the possibility, and then find out where they live. Some people just want to talk, share experiences, share ideas. If you aren't interested in developing that with someone who is too far away then just politely bow out of the conversation.
