If we express different genes through our lives because of epigenetics, does that means we transfer different genes to our kids depending on the time of our lives we had them?

No (but sort of yes). 

What you're describing is epigenetics, which are not genetics per se, but does influence which (and how) genes are expressed through epigenetic markers usually made from proteins. It has been found that (at least some) epigenetic markers can be passed to offspring; so while the genes that are passed won't change through aging, the epigenetics may.

One pertinent example of this is the finding that extreme stress can leave epigenetic changes that are passed to offspring (in mice).
