Hi doctors - based on other things I have read here, I believe you will tell me that this was a virtually no risk event, but I figured it was worth asking about.

I have been visiting a sensual massage provider for the last few weeks. Generally, the service offered is strictly hands only (massage ending in a handjob), which I know is considered safe. However, the provider and I have had some good chemistry and she knows I am very careful about my health, so she offered to perform oral sex with a condom, if I had one, which I did. The condom was made of Polyisoprene, not latex, although I believe they are similar in their levels of protection. 

So for about 10 minutes during my last visit she performed oral sex, taking my covered penis deep into her mouth. At no point did she go beyond the edge of the condom (so my skin did not go into her mouth). And while I felt her teeth occasionally, the condom seems to have stayed perfectly intact. After a while she removed the condom and brought me to orgasm with her hands. 

I get the sense that she is a generally  safe, good person who really cares about her health, and who would want to look out for the well being of her clients as well.

That said, because I have a partner who I have been with for 20 years (the only person with whom I have ever had vaginal sex) I want to make sure I do not put her at risk for anything.  We are currently using condoms to avoid pregnancy, FWIW. 

Is there any risk to me or my partner for an STI? Can I resume normal

activities? 

Thanks in advance.
