answered you on std since you weren't getting a very good answer there but yes, hand sanitizer is fine.
remember - you are not a walking biohazzard!! keep reminding yourself!!
After fingering, masturbation, or using the restroom is using germ-x as good as hand washing or should I wash my hands?
I was advised to post this question here too so I'll post it with this one! Sorry to be a bother!
And I apologize for asking questions again!
