What's the deal with these gay "husbands

So i've been in the life for about 10 years, i'm a"BBC BULL" I started off at parties and then moved on to on finding couples online. it seems that in the last couple of years i 've seen an upswing in the numbers of couples where the husband want to suck my cock. i don't have anything against gays, but i'm not gay so i'm not down to let a guy blow me. it usually comes up in conversation with the wife, they tell me that their husbands want to "fluff" or "clean up" after. it's usually not a deal breaker for them, but sometimes they will try to push the issue after the fact. i've had to leave a couple of couples, because i didn't feel comfortable. i've been servicing this "hot wife" for about a year, i've told the husband about how i'm not cool with guys wanting to blow me, and how i think its a trip that it happens so much. so last night i'm we are in the bed and she asked me about a duel blow job. at first i though she wanted to suck us at the same time, which i wasn't cool with anyway g. but then i realised she wanted them to blow me. when i told her no,he chimes in "yea he is straight". i'm really surprised that he would even try to go there. maybe he is looking for an excuse to get a different bull for them. but whatever the case is, i'm going to have to have a talk wity him, and set up some rules, or no mas. i'm wondering if it's just me, or are any other bulls running into this issue.
