Should i give my DH sex on demand?

[ShiftShaper]

since having my dcs i have no sex drive whatsoever. i love my husband dearly and find him very attractive but sex is just not on my list of priorities anymore. the kids are now 3 and 4 and my libido is nowhere to be seen, which doesn't bother me one bit, although maybe it ought to.
i really feel for my DH, he is as sexual as ever and while he patiently waits for me to be in the mood, he could be waiting til doomsday...
my question is, should i have sex with DH to let him get his kicks even though i am not interested in an orgasm? i love the closeness and he loves the affection and he gets his oats too.
is this a really weird arrangement to come to?

Good advice from both selfishman & prufrock - but half the battle is kind of feeling like you want to try to want to, if you get my drift. If someone's fed up with the sex-hungry partner for other reasons, resenting that person for never helping with domestic chores or wanting to do anything enjoyable with/for the partner that doesn't involve sex, or if there are other major tensions in the household (money worries, other family quarrels etc) then 'permitting' someone to have sex on your body will not improve the domestic vibe.
Glad to hear things seem to be working out OK for the OP, though :-)

i definately find that the more you do 'it', the more you are interested

i find though that i am inhibited because i am sooooooo scared of getting pregnant (whilst on the mini pill - a good one as effective as the full one). any tips?
