Not nearly enough!
I have my long term guy who is more friends now (but occasionally with benefits), plus a couple of FWBs here - but a matter of getting with any of them is sometimes tricky because of conflicting schedules, or in the case of the long term guy, distance between us and his medical problems.
I'd say I average about once a month now, but prior to July of this year the last time I'd had sex was December 2000!
And I've gone through
all my sexual peak years having very little sex (despite my extremely high sex drive - that more than one guy I've been with has commented on!). It's not necessarily true about women can get sex easily... maybe if you're a "hottie" but not if you're an average looking and shy woman. I've had to go out and look for it myself, since it wasn't coming to me. My FWBs are the result of me actively looking...
