I'm a guy and I would love it. Of course, I'm bi (Kinsey Scale 2) and always used to swallow when I gave blowjobs to the one guy I was ever with. I usually swallow my own after masturbation.
I wish my wife was into snowballing or letting me eat my creampie out of her, but she thinks it's gross! She won't swallow, either, although she lets me cum in her mouth all the time. She says my cum tastes good - I read up a long time ago on which foods to eat and which to avoid to create good-tasting semen, and I stick pretty closely to that diet - but she's just grossed out by the texture. Also, she says she's worried that the testosterone would do funny things to her! Oh, well. Can't have everything.
