1 doctor agreed: See ophthalmologiist: Light flashes in the periphery of your vision are usually caused by either a problem in your eye called vitreous detachment or ocular migraine. You need to see an ophthalmologist soon for a dilated eye exam to be sure your retina is OK.
A major difference between the female and the male orgasmic phase is that far more women than men have the physical capability to have one or more additional orgasms within a short time without dropping below the plateau of sexual arousal.
Of course, these are just averages and some women and men may experience longer or shorter orgasms than others, by a tad, but relatively speaking orgasms are a similar-ish length of time. No one, for example, is having 5 or 10 minute orgasms, to my knowledge anyway.
