I am a male and have had a swollen area

Patient: I am a male and have had a swollen area above my groin area behind the public hair. This rarely causes pain but every now and then it hurts. I can push on it and it feels like there is fluid there, and it goes to the normal state as it is be, like the right side (left side swells). It has been like this for a while, I am 19 and was wondering if I could get any more information or if anyone may know what this is. Sorry about the bad explanation, if someone has an idea and needs to know more, I can describe it better if asked.

Symptoms: Swelling
