lol, yes some of the stuff i read on here does make me wonder...
i, or i should say 'we', keep doing it because it's fun and excitement for both of us. the butterflys you get from meeting someone new, the excitement of being in their arms, the arousal in seeing their eyes light up when they know you're going to fuck. the jealousy i see in hubby's eyes (i don't know why it excites me but it does - it excites him even more!). reliving the whole experience again when i tell hubby and see how insanely it turns him on.
i should mention that i'm not overly attracted to black men (yes, i realise how weird that sounds on a site like this). the excitement is more to do with the illicit nature of sleeping with other men. i actually prefer white nordic men!
and whilst a large cock feels nice. sure it does. the best sex i've had isn't with the guys with big cocks. at times i crave that full/stretched out feeling but it's not like i don't enjoy sex without it. far from it.
