what do I do?

Em
I am 14 and just asked how do I give a hand job on a post and someone replied with that has me stunned that someone gave your an answer and guide you should be focusing on school and grades. I have never had a boyfriend or kissed a guy but I think I have a high sex drive. I feel guilty for thinking about all this and looking up things like that and wondering things like what is cum? I also feel guilty and dirty for wanting to look up porn.
