I have that problem.

it cropped up last summer, when I had a TN-type flare.

I had the netherworld-numbness before, and it went (mostly) away.

but THIS time, well, it's been 8 months, and it shows no signs of leaving.

I am grateful that the plumbing still all works, and the area lubricates properly, but I am unable to achieve orgasm with my husband, during intercourse.

our solution is to use a vibrating device (a cordless, rechargeable massage unit), which DOES still punch my ticket, so I get my desert first, and he gets his fun afterwards.

we've also had to adjust our positions, as my legs spazz out totally with the standard Missionary position... wang-chung go the hamstrings, and the calves go WAH !!

for most people, having MS needn't be the end of a happy sex life, one just must keep making adjustments.

and good communication with your partner is the key.

oh, and towels, lots of towels... and maybe even a mattress protector.

fear, worry and tension can stomp out even the biggest flame, so, plan ahead.
