Don't confuse me w/ an expert. From the discussions here on retention there is a real controversy if 'forced' celibacy particularly for the youngish does more harm then good. Clyman admittedly has some juice but is not without controversy (and a bit of ego IMHO).
Instead of sweating out 100 days of celibacy you may want to consider another gi gung route. I like Michael Winns products, many of are fans of his Primordial Chi gung. I really like the routine on Fundamentals I video and his Fundamentals II has a nice routine called Pangu. Plus he's a accessible teacher. Course he's not w/out ego or controversy. Hell everyones controversial

.
What I'm saying is Clyman's isn't the only game in town. If you have the time and inclination read through some old posts to see what people here have been into. Certainly the practice dujour is Lama Max's Kunlun(see hell statment). Thats not to say we're all lightweight guru hoppers, but he certainly looks interesting, accessible and highly juiced.
Look around, see what path has head and heart.
