Hi and welcome. I guess the logical question is: has sex ever excited you? With anyone? If the answer is no, then you're probably just naturally LL. This doesn't mean you can't try to discover new aspects of your sexuality, but that you should also work on accepting yourself (lovingly) the way you are now. If, on the other hand, sex HAS excited you in the past, then it suggests your DH isn't doing it for you in some way. The next step would be to figure out if he can change something in his presentation (appearance, technique, foreplay, making you feel desired all day, whatever) to get you more inspired.
Are you getting enough sleep and support?
You asked if sex has ever excited me?
I think you are on to something.
When you see it coming, duck!
I agree with the posters who encouraged you
Yes, and something about a string of piss-poor excuses from a LL that you both know are falsehoods just adds fuel to the fires of discontent for the HL. I would have so appreciated my DW just admitting that she didn't know why her desire dropped but she was willing to go through the motions to please me as best she could and maybe with time and a little discovery, things would return to what they were.
It wasn't until I put all of my DW's 'reasons' to the test by facilitating each and every one that the real issue surfaced. Sure, we're divorcing now, but we both seem happier than we have been in a long time and I feel
a wave of personal growth
DW certainly related to the LL during breastfeeding - the exhaustion, touched-out feeling and the effects of oxcytocin all took their toll - and the breastfeeding was very extended.
I was prepared for that and was fully supportive of it, even if it meant minimal sex.
