multiple partners

I feel awful about my previous sex life, but am worried if it's really okay for me to change.

I'm very embarrassed to say that over the last year I have been very promiscuous, as in to having sex with 15 different partners. I have gotten over that phase, and I have sworn to stay celibate for at least six months. My question is whether or not it is possible for me to be tight again? Also, if it would be right for me to make a future boyfriend wait a while, before having sex with him?...
