36hrs in plastic pants

I was so turned on last night.
By morning it has been 36 hrs in plastci pants.
A day and a half to go.
She asked me last night how long could I abstain.
In a way exciting but also she wanted me to choose a duration.
It would be much easuer and funner (less threatning) if she were to say - 2 weeks or 200 weeks whatever.  Mind you I do not want 200 weeks.
2 - 4 weeks would be a challange but also with the prospect of reward.
