Chastity and orgasm denial discussion

I don’t currently have a keyholder. However, I’m keen on trying self-milking since it’s something new for me.

Could anyone offer some guidance on choosing the right protrate massager? Also, what’s the proper way to use one?

Plus, I saw in a magazine that you might not feel an orgasm at all during this process; instead, it just feels like urinating when the sperm comes out. Is that accurate?
