Novices and newbies discussion

About nine hours ago I gave my holy trainer’s key to my friend and former girlfriend, Alice (name changed). She also received £60 as a sign of thanks. The device is comfortable most of the time. When it feels too tight, I know to add lube or use the toilet. Despite that, sleeping was tough last night. Emotional excitement likely played a role since I’ve wanted this setup for ages. It should settle down somewhat as I adapt, helping me fall asleep faster. My lower back also hurt while trying to sleep, which didn’t help much. The horniness is another factor, and I fear it might increase the longer I remain locked up. I only got three hours of rest last night, so I’ll need more in the coming days. Alice was somewhat unclear about when she will return the key next. She’s away until Monday at the earliest anyway. I’d love to hear from anyone else who has faced similar problems and any coping advice would be wonderful! Thanks!
