No one going into university is a virgin. Just like university is like all those adult videos about college you see on the internet with alcohol, drugs and girls throwing themselves at guys.
I should insert a notice here that sarcasm was used extensively in the previous paragraph.
Whoever told you that being a virgin is unusual and weird is so stupid that to point out to them that they are stupid would be like trying to teach a dog how to fly a plane. Don't argue with a stupid person because they'll beat you with experience.
