Pavel Novotny springs rapidly to mind, awesome bod and hell of a cock.
Rex Chandler, another great bod.
Forgot to put Cody Foster, but alas he's not with us anymore :-(
Yes, they all made my heart (and hand) beat a little faster for as long as the short duration of their porn careers.
Also Sean Colby in Matt Sterling Scorcher or that Southern beauty called Lance by Pink Flamingo, all performers I would have wished had done more porn.
I suspect we shall never find out if any of those ex-porn stars ever keep copies of their youthful performances in their HDs and go over them once in a while in their mature years like Yeats once admonished someone:
WHEN you are old and grey and full of sleep,
And nodding by the fire, take down this book,
And slowly read, and dream of the soft look
Your eyes had once, and of their shadows deep;
How many loved your moments of glad grace,
And loved your beauty with love false or true,
But one man loved the pilgrim Soul in you,
And loved the sorrows of your changing face;
And bending down beside the glowing bars,
Murmur, a little sadly, how Love fled
And paced upon the mountains overhead
And hid his face amid a crowd of stars.
