So I'm 15, and sex is a thing that's on my mind. I always told myself that 15 would be my youngest, and I think to myself I'm ready. I have moments where I feel like that's all I want and others where I feel like it might be a mistake. I'm currently in a realtionship with this guy I really like, he's also 15 and we have been together for 4 months now. I have known him for 4 years though. He doesn't ever try to push me into doing anything, and we have talked about the topic as we are quite open. I feel like I want to, but I think I should get advice off someone, more experienced, to make sure I'm not making any mistakes. So please help, as I'm very confused on what to do? 💕
