Rubbish Orgasms?

I can't find anything online in lists of symptoms so might just be me, but worth asking...

If you can get over the lack of libido, tiredness, dryness, rage at your partner and anything else that gets in the way and actually get round to having sex or masturbating, have your orgasms changed?

I'm finding it's there, it builds, there's some kind of release but I'm left feeling a bit 'o, was that it?'. My partner is great, he puts in plenty of effort, we're doing what used to work, we're trying some new stuff. It's the same if I'm by myself so definitely not a him problem.

It's just annoying to make the effort, overcome the lack of libido and actually try doing something sexual and then find it a bit meh.

Anyone else got any thoughts?
