DP and I have each had a lot on our plates lately, enough to mean we're pretty much dealing with our own stuff alone as opposed to sharing the load. We've been distant, there's been practically zero affection (physical or verbal) for quite a while and DP is quite an insensitive individual at the best of times. I have very little sex drive, probably through a combination of sleep deprivation, still breastfeeding (>1y) and stress, but I believe a large contributing factor is the lack of spark between DP and I these days. DP has previously expressed how important he views sex as part of a relationship and he has a much higher sex drive than me. He'll randomly ask me when DC has gone to bed and I'm in the middle of working if I fancy a quickie, and the honest answer is no.
I feel bad because I know he "needs" it more than I do at the moment. AIBU to say no (repeatedly) if I'm not feeling it?
