The only sex risks are unprotected penetrating vaginal or anal which you didn't do. Touching HIV or oral sex is not a risk because HIV is instantly inactivated in air and also in saliva.
If the sw supplied the condoms they are protecting themselves against their customers, in which case they likely are negative anyway.
If a condom fails it is a large rip down the seam and all you have left is the base which both of your would be aware of.
I hope that is all you need to stop worrying, because you didn't have any HIV risk and don't need to test.
Your doctor is the only person who can diagnose what you feel are bumps, but it isn't HIV and this is not a diagnostic forum for non-HIV issues.
