No I don't experience the same thing but I sometimes think my wife is less warm & loving & attentive afterwards once we've got up - makes me feel like she actually had a lot of other things on her mind that she wanted to get on with and once we're up she seems busy & focused on "her" agenda (actually i'm sure this is aprtly true) even when I'm helping or we're sharing any household jobs that need doing - that aspect of being together afterwards is something I don't like but you're saying you feel low and that is just you - not the interaction afterwards?

I've never heard of the idea of semen containing natural anti-depressants - it sounds like complete bull to me and even if it did I can't see how their presence in the testes would be of any benefit - I think they'd need to be in the bloodstream to help. Surely the quantity (if any) and efficacy would be very small anyway so I can't see that it would be a noticeably factor in feeling low afterwards - if anything I would expect the rise in endorphin levels to have an overall positive effect. The unpalatable (and completely impractical) solution (pun intended) would be to eat your own semen wouldn't it - would that balance things out? I can only imagine it's perhaps more to do with low self-esteem and if that's the case perhaps you need to delve more into the reasons for that plus I think we can all train oursleves, trick ourselves, convince ourselves that something is true and then get into a habitual way of looking at something when in fact it could be groundless and you just need a shift in your thinking.
