Yes, but I don't think the gov or these places care if people are cheating on their partners or not. Aside from that STD's are like any other infection you might pick up.
Prelib and all those are fine, yes - but just so you know - the results go to your DSQ, which your family doc will look at. Just FYI.
That's why I recommended Sante Medic. None of that, and cheaper.
