There is no risk at all from the massage or handjob. In theory, there may be a very small risk from the attempted sex, but it's not enough of a risk that I'd worry about it at all.
You don't know what kind of spray she used on you? I hope it wasn't an antiseptic, or worse, something like bleach. If you get any irritation, it could be from the spray, and you'll think it's an STD.
Really, though, the chances of you getting anything are theoretical and very, very close to zero. I wouldn't bother to test, even if you do have a regular partner.
