Hubby here.
Wife asked to do this fetish a year and a half ago. I was worried about her safety, and a bit insecure she'd leave me. Also, I have two ******* from a prior marriage, one a teen living with us. I didn't want my ex to know, so the kid couldn't know. Not trivial.
Safety: I communicate a bit online with bulls here so they know I'm real. Wife doesn't give address, telephone, text etc. info. Prefers to meet them in person soon to know if they are real. She picks place, a local black-owned restaurant whose owner knows the game, has met me. No sex first date. If goes well, may exchange phone #s or emails.
Relationship: yes, was a bit insecure when I learned it was more than sex with bull. Solution was for me to date. I now have a great GF, gets along with wife, knows her fetish, has her own, etc.
*******: teen does NOT know. Met one bull; was told (truthfully) he knew step-mom from work. My adult ******* knows and is fine with it. As for computers, I take computer security very seriously; passwords, parental controls, etc. Do it.
Play at home: yes, when ******* GONE and a man we both know and trust. Example, earlier this week, a bull met here on BtW messaged wanted to spend wednesday night (tomorrow) overnight; he has done overnights here before. I said I needed to make kid arrangements. He was fine with that (actually, he had to cancel). But, I liked that he and I had the relationship that I could coordinate plans with him.
Summary: yes, it works. Takes planning and cooperation of you, hubby and bulls. BTW, you may fall in love a special one. That is alright. Let your hubby date, too. ;-)
