Novices and newbies discussion

Hi all, My girlfriend and I have been doing honor system chastity, meaning I’m not wearing a cage but I abstain from masturbation. We’ve used a cage intermittently over the last year. My shortest period was 24 hours and my longest was three weeks. Our wedding is coming up on a cruise soon. We won’t be sharing our room the night before, and I plan to go out with the guys for drinks. I know that when I return to sleep in one of their rooms, I’ll likely be very tempted to jerk off one last time while still single. (Before meeting her, I used to masturbate twice a day, and she caught me several times; she really dislikes it when I touch myself.) The last time we were intimate, I got so horny during oral sex that I blurted out how likely I was to jerk off the night before the wedding… She wasn’t happy about this. She stopped what she was doing and told me I better not do it. My response was that it’s my last chance as a single man. What should I do?
