25 [M4F] #Online - looking for support

So, what I'm looking for might be a bit unconventional - I'm looking for someone to help me stay in chastity while I'm away from my girlfriend.

Current situation: her and I are together only over the weekends and that won't change for the next few months because of her uni schedule.

The problem: I'm a bit needy and jerk off during the week, so when we're together, my sex drive isn't too high.

Since she's mostly vanilla and I don't know how this would impact our dynamic since she's not really into being dominant, I don't want to burden her with keyholding. Rather, I want to lock myself up and then have a "buddy" to help me through it and support me.

I'm not here looking for a sexual relationship, but rather someone that helps keep me pure and hopefully becomes a new friend in the process since in my real life, I'm not really surrounded by kinky people with whom I can talk about topics like this. :)

I'd love to meet any and all people that find this appealing or have any advice for me, feel free to drop me a DM!

P.S. For anyone that finds it important, I'm a 25 year old boy from eastern Europe, 175 cm, 75 kg, muscular but not fatless.
