Female led relationships discussion

My boyfriend and I are keen on giving chastity another shot. (We attempted it before, but it was a disaster because the device didn’t fit properly). We’ve researched various devices and are now waiting for a trial unit to arrive by post. Since my partner and I have been together for 2.5 years, we’ve always dreamed of building a family. I’m 21 and he’s 22; we’re heading off to college soon with plans to move in together, marry, and then start our family. I’d love to hear from any women here who are planning to have kids or already do. Is chastity truly safe for couples aiming to grow their families? I want to avoid changing his penis or balls permanently or causing lasting damage. Do you think it’s the right path for me? Missy
