Neurotic in LA

hi all - just found this board and appreciate the thoughtfulness of the community. i've read through a lot of posts and have a couple of questions...

my girl and i have been thinking of swinging but we (mostly me) are neurotic about getting an std. do people show up with recent test results or verification in hand or is it a trust / honor system?

i'm wondering if there are any websites where you could have your results available for you to show or e-mail to people you want to hook up with. any thoughts / feedback would be greatly appreciated.

thanks!
