I think it's a good path for many. It's really up to the couple. For us, it was me who encouraged him to give a bj and take a guy anally. I don't think he would have done it otherwise.
Does he like it?? He won't admit it outright, but he has given several bjs and taken guys inside him many times. He moans like a girl too. I so love that.......
I think a good test is the whole 69 position for the couple as the bull is doing the wife. When he comes in her and she lowers herself right on his face, that's super close to swallowing.
