Chastity and orgasm denial discussion

Hi there, I’ve just joined the group and I’m based in München. Chastity is a new topic for me, so I have some queries regarding it as well. When I’m wearing my device and feeling quite turned on, I sometimes see that (please excuse my English, since I only know these terms loosely from German!) the area at the bottom of my penis, just behind the chastity cage, tends to swell and bulge out. This happens mostly when I am straining hard for an erection because my mistress is teasing me about it. Is this considered normal? It doesn’t hurt (just a bit of stretching). Currently wearing a CB6000. Also, can someone make you ejaculate while still locked in, without using prostate stimulation? My reason for asking is that if the mistress causes ejaculation but not orgasm, my lock period extends by two more weeks. She has attempted this before; it left me feeling quite frustrated, though there were moments when I felt like I was about to shoot. Thanks everyone, W
