First time lock-up

Hi guys,
I bought myself a cock cage on impulse and locked myself in it immediately. I've been locked for 48 hours (slept, showered, went to work, etc) and was wondering how long people thought I should stay locked for my initial lock up. I know that if I don't have a set time then it'll be a contest for myself and I probably won't unlock myself until the next time I think I might have prospect for having sex (been in a dry spell for over 9 months, so that might not be so soon).

I don't currently have a key holder. (Living in NYC if anyone wants to try and take that role.)

It seems that the winner is to tease. Just for a little more background, I'm in my 20s and I am not a sissy at all (nor am I trying to be). If I was more aggressive a person, I imagine I might be considered a good candidate for a bull, but I'm more into romantic sex. I locked myself in chastity because it's just something that's always intrigued me. I've now been locked over 6 days without any release.
I guess my next question is, how frequently should I tease? I should also mention that before I went into chastity I had gone over 8 months without cumming and on a different occasion I've gone a couple months without, while doing constant teasing and edging.
For me, this is more of a game until I actually find a keyholder, but I am interested in all of your thoughts.
