OK but can ARS manifest itself as just muscle aches. I am not prone to aches and pains and at week 2.5 I developed this really bad pain in the back of my neck that come and goes but still persists. The pain in the front of my thighs was very odd and lasted two days .
Yes you are very right Teak,,, I missed this point
If you were so intoxicated that you don't remember then you were to intoxicated to get an erection.
No this does not look like ARS. If you did not have any unprotected penetration, your risk does not exist. However since you, yourself are not sure, get tested after 3 months time to get a conclusive test result and move on with your life.
Next time keep alcohol and woman separate, they do not mix well
