Help for Genital Warts

Well i had sex wit a guy a week ago and he DID wear condom but i found a raised bump near my anal area.not trying to be nasty but thats where it was. Im scared that this is HPV but could it just be a cyst?? it is just a single raised bump but i read about hpv and it says it can also appear as a single bump =( help im scared =/

for nurses and medical allied (doctors, pt, etc..) what is the difference between bartholin cyst and genital warts? both have the same symptoms and features?
