Most men I know are straight and straights are mostly all the men I ever knew, despite some surprises later in life. It was just the default assumption and figured into any fantasies I had about them sexually. There is a site and torrent here, Beautiful and Agony are the key words:

What you get is short volunteered videos showing only the faces of men achieving orgasm. Mostly they are wanking, a few are getting blown (some by women), and they get more and more engaged, they climax, and then they lay pleased and blissed out and we watched. Hot stuff and it's not their fantasy or helper who gets our attention, it is the man getting the result we all want all our sex partners to achieve.
Also, I like knowing something about the sexual experiences of my straight partners and how that relates to what we are doing. They often have extraordinarily lucky women who may have no idea what they are getting.
