Sexless

It has been almost a year and a half since I've had sex and, strangely enough, I'm not exactly upset by it nor eager to pursue it. While I'm caught up in being a full-time worker and a full-time student, those are just little contributers to a whole slew of them. I'm also very hesitant to give my body to just anybody and, although I don't need a solid commitment because fuck buddies are healthy for an active lifestyle, I also need SOME sort of spiritual and/or mental connection in order to engage in the act! I suppose my question is this... after over a year of no sexual human contact, what could attribute to this? Also, I should add, it can't be my lack of interest! I am definitely a freeeeeak haha
