Don't take it personally, that's what happens in nature as males and females age, and as the relationship ages. Contrary to popular belief (in the US especially) love and sex are totally different things - they can be related but still they are totally different experiences. As a matter of fact the term "make love" is very misleading and just sets people up for problems and disappointment - it says "he doesn't LOVE me unless we bump our private parts together". Call it what it is - "having sex" - so you don't set yourself up to blowing it out of proportion if in fact his desire to bump private parts together decreases as it surely will like with every other male on the planet as nature intended. Nature bumps private parts together to make babies. Nature also gave us something else called love which is much much harder to find and experience and is far more rewarding don't you think? If you can agree that "making love" is not in fact "having sex", what is your definition of "making love" now? Does he still give you that?
