Found what looked like 1 red pimple near butt crack-it was really hard to pop but i did it and clear liquid and blood came out. herpes?

Needs to be cultured: We can not say what it can be without examination prier to be popped by you, but if there is still some fluid there it can be cultured for herpes and other bacterial infections so go and see your doctor to find out what it could be.Unlikely to be herpes but bacterial infection a possibility.

Difficult to say: Here are some facts. A blood filled cyst near the anus is a hemorrhoid. Herpes lesions are blisters or a cluster of blisters that do not have blood in them. They also hurt and itch. Sometimes with a large bowel movement a small tear can occur that then gets infected. So, an infected anal fissure is a rare possibility. But, a pimple is also in that realm.
