GF tired during sex

[xyz221]

My gf always get tired during sex, when I ask her about orgasm , she says that I don't know but my whole body starts paining mainly thighs and vagina. what does it mean?

PS. initially during foreplay she is really horny

For how long does the vaginal penetration go? And what sexual positions are used?

My wife gets sore from drying/loosing lubrication during the penetration the longer it goes on. And her legs, maybe thighs get tired when they're lifted up for a while, so we let them go down after some time for missionary style if they were lifted up in the beginning. As for the penetration time, I have to aim for a sweet spot interval where it's long enough for her to enjoy (that I don't ejaculate too soon), while also not take too long to get her sore.

So you could try other sexual positions, or try shortening the penetration time, maybe try ejaculating sooner, if you are able to last a long time.
