Got a massage and more and now worried.

Kinda ashamed to say it but yesterday, I went to a massage shop in CBD. At the end of it she asked if I wanted more. I agreed to the price (150 for the extra part)

Small bj followed by the deed. The condom was intact. I finished in the condom. While going back home and now after waking up, I am feeling the shame of act and a bit scared about the STDs and STI.
