Risk from possible dipping

[miromito]

Hello,
three days ago I had a hook up with an older guy. We played a bit, frottage first against my anus, then he pressed his anus against my ****. It all lasted quite a while, and with no condom. I don't think there has been any dipping, but I cannot be sure because his anus was very wide and he often put lube on (while I kept my anus as tight as possible when he was pressing against me). I repeatedly asked for a condom, but he always procrastinated. After maybe half an hour, when it was clear he just wanted to bareback, I said I felt uncomfortable and he made me come orally.
Sorry for all the details, I just got nervous because I believe he's positive. There has been no full penetration, but still quite some playing. I will surely do the test in 3 and 6 weeks, but are there really reasons to worry?
Thanks

If penitration then a risk, if not then no risk.

I got a canker sore today in my mouth, but it might be related to the stress, rather than the encounter itself.
