Why is it that some females during sex find themselves getting sore/ dry?
Answers: Lack of lubrication can be a hormonal problem, or psychological. If you are not feeling up to the stroke with someone, next psychological. If you are interested but it happens, consequently possibly hormones. You can try using lubrication such as K-Y.
Not enough foreplay, not really into the soul, sex is going on too long.
Try more foreplay, or use KY jelly
Can be lots of reasons. Age, standard health, where on earth you are in your cycle, even what medication you're taking. Something like benedryl (pseudoepiniphrine) will dry out your body as a side effect: dry mouth, dry eyes, and dry... everyplace else!
It's pretty adjectives, which is why they have lubricants.
Same reason why men can lose their erection. Could be you are getting distracted or not enough stimulation for example.
Try to hold your mind off of things outside the sexual leisure. You will need to lose yourself within the sensation, it will be tricky sometimes.
Look for things which turn you on, and do them more often e.g. see his penis, squeeze his butt etc. whatever make you aroused.
