Please help/give advice I’m 16&never been kissed&never been to a house party

So I’m feeling a bit depressed recently because I’m 16 and never been kissed and also have never been to a house party. I look at everyone in my school and on the weekends they’re at parties and I’m not and that’s kinda where most ppl kiss people aswell. I’ve had guys like me but not that i like enough to start a relationship with. There was also this guy at the start of the year who I sat next to in a lesson and liked but the seating plan changed and so I can’t speak to him and it’s too late to snapchat him or anything Cas it’d be weird because we don’t talk anymore. I really don’t wanna feel down about it all and want to focus on exams and stuff but recently I can’t stop thinking about it and Im feelin kinda depressed. Please help/ give me advice
