People can surprisingly last... I mean waiting until marriage to have sex. It's just not very popular because 1. Not many people are religious. 2. There's many ideas that say against sex before marriage. The problem is with the new age society (I'm not talking about zoomers exclusively) It advocates sex so much like it's a necessity. Yetim bihon, people can have sex at any age now because your friends and all the movies tell you to do it. So you start having the need to fuck someone. Heck, you don't even need to be in a relationship to sleep with someone. Being that, I still believe sex should be with the one soulmate. It's a struggle to live against such a general idea. Also, perhaps you could just avoid relationships at such a young age. This will help you avoid this issue completely. Netflix is dreamy, but dreams aren't real.
