See many other threads over the past 2-3 months about the (low) risk of STDs, especially HIV, from oral sex. Also note that if you didn't develop symptoms by now, you probably didn't get infected.
Search for "STD from oral sex", "fellatio", and "STD transmission by oral sex".

That only talked about herpes, I am worried about other stds.
