What can I do if I have no privacy to masturbate?

I used to always masturbate at least once a day before I came here to college. However, now that I have a roommate, I can never find time alone to masturbate. I feel a need to masturbate at least once a day, but now I can't go through with my urge every day. Thus I start thinking about masturbation during class, and it's really affecting my mind. I need to masturbate or else I can't function correctly. Please help me out. Maybe there is another means to get out my sexual urges.


How many rest days should I take between runs?

I wanted to know how many days of rest is recommended between workouts. I heard it was three days on to one day off...is this enough? I workout on a treadmill for 50 minutes every day and have for the last 14 months. I was not aware of how rest played a very important role until I recently read a brief article on it. I guess my question is, do I need to take that day of rest and how important is it?
