Interesting thing started happening after using aneros

I got a helix syn a couple months ago. I’ve used it a fair amount of time with no real success besides a hands free wet orgasm, but still fun. I often put it in before sex and the other day while in the shower having sex i started to get close to orgasm so i pulled out and gave my pc a squeeze and ejaculated once. It wasn’t a full orgasm but still felt good, after that I was able to return to sex and repeat the process another 4-5 times before having a normal orgasm. Has anyone experienced this? Since then I’ve been able to do this without the aneros while masturbating or having sex.
