Is Axcite only for the first stage of the game to help enhance the chemistry between you and your woman, or does it enhance....other things like performance and stamina?
Good question! I think that the answer might depend on the person, or the couple, really. The scent is an attractant for sure, but if the couple are more into eachother as a result, then the ensuing 'activities' might also be enhanced. Does it have an outright affect? I don't think so. But by proxy, I'd say yes! On the other hand, if you were to "stack" AXcite with AXcite Magnum, then performance and stamina wouldn't be the only things "enhanced".
It can have a mild effect on your sexual prowess, but nothing to hold a candle against a little blue pill. As Tim mentioned, AXcite Magnum is what you are looking for to handle that department.
