I'm new, but kinda not, and I got some questions...help please....

Hellow, I'm a bit of a chastity lover, and I've been into it for the past 4ish years, but my first cage was kinda crappy, so I had to get rid of it; because, it cut my testicles a little. I am a current college student although I'm home for the Christmas break, and since I have recently gotten a new cage to last for life, I have been noticing some issues I've never come across in my 4 years of learning about chastity. So I'm planning on joining the chastity mansion community, but for now, I just need answers to a few questions I have.
Question 1. So I have recently been caged less than 24 hours and I have never been able to spend much time in a cage due to the reasons above, but I noticed that my right testicle has been hurting a tiny bit and started last night. It's not unbearable or even very painful it's just very discomforting as of right now. If it helps, I've always been a guy that hangs to the left so I'm not sure if this is normal or just a me problem.
Question 2. As I have been dabbling more in anal pleasure, for the reason of knowing i'd be going into chastity soon and that would be my only way of receiving pleasure, I noticed a white, flaky, secretion that would show up on the toys I'd use on myself; after, I reached orgasm. (so like I have a dildo in my ass and cum then there's this stuff on the dildo). Is this like an anal secretion of some sort, or do I just need a doctor?
