I like oral better for the main reason that I don't get it too often (hurts my girl's jaw) but when I do... boy o' boy it can be somethin' else. It doesn't always happen, but sometimes when I orgasm from getting head, my whole body shivers, I get light headed, and my muscles don't really work right (if I tried to stand up I would probably fall right over)... that shit's awesome.
Very funny, prick =P She's been looking into birth control, but she has a cyst she needs removed, and will be put on anti-biotics so there's no point in starting until after she gets around to that.
vaginal feels better by far, but babies don't come out of mouths so I like cumming there more. Besides, my gf says her orgasms are more intense when I go down on her, so we just 69 FTW!!!
