Do you have these weird thoughts?

I am 17 and I am not sure if this is a fetish or not but I have a strange one where I image my self being infested with a alien virus and told I must repopulate and I must do that by having *** with women. I am not sure if this is me but I think I may have been watching way to much Species. I keep fantasizing that I am some infested human with alien stuff and I have to go around and have a org* with them. I always think about creating some kind if nest by mastuebating and then reaping women inside so there will be endless ****ing to the girls. I also dream that I have toget more women. Am I the only one with these weird thoughts?
