I am 15 and I am still a virgin. Yes it is normal to be a virgin at 17. Dont worry. My dad lost his virginity when he was in his twesties, so I really wouldnt worry. Not alot of guys lose their virginity at your age and the more that do get STDs.
It's totally normal. There are plenty of guys your age or older that are still virgins. There's nothing wrong with it. It's not something you can force. When you do have sex, use a condom!
