Chastity Used to Address Delayed Ejaculation

Hi everyone. I’m new here, which is why my username reflects that, so please bear with me. For the past couple of years, I’ve been struggling with delayed ejaculation. During PIV sex with my wife, I can’t seem to reach completion, and she struggles to help me finish manually as well.

We both want to add some excitement to our sexual relationship, and I recently gifted her a magic wand which she has fallen in love with. She now uses it during every intercourse session, allowing her to orgasm within 10 minutes. Once she is done, the dynamic shifts to me trying to finish until she becomes sore and exhausted. We have been together for ten years and are married.

I found some online suggestions that chastity devices could assist with finishing more quickly and would offer a fun new experience. My wife has asked what she can do to help or if there is something specific I’d like to try, so I know she will be open to experimenting. I am curious if anyone else has information on this particular topic. Has anyone introduced chastity play into their relationship when the man suffers from delayed ejaculation? Thank you.
