This subject is always a tricky one. Not quite a double standard, but I don't ask for certs because I feel it is up to the individual. But as a single male, often certs are wanted or needed to even be considered, so it is interesting to see the back and forth. I do not have any current certs, but I have had amazing fun with couples and singles that I have met. I've sent them certs, but they choose not to post, which is fine and their call...
Just meeting cool & fun people is the goal, if certs are posted, great, if not, that is cool as well.
Have fun and play safe!
