Vegan sex drive is this normal?

Likely it is caused by an increase in circulation. Improved digestion leads to improved blood flow, which leads to - voila!

I can't see why that'd be the case seeing as raw vegans typically putrify fat as some horrible nutrient despite it being absolutely vital for hormone productions, some of which are the ones to cause libido.

Oft its the opposite as you say, 30bananasaday folk & raw vegans complaining of a lack of sex drive.

Chances are you're just eating an all round healthier diet from going vegan which of course would make you feel more energetic & such. Its not the exclusion of meat and animal products but the INCLUSION of other food groups like grains/beans/nuts/legumes in high quantities that could cause this

That's all fine and dandy, just give it a bit of time. Enough time for your hormonal profile to start changing significantly, cholesterol to decrease, and your body being sluggish to make hormones etc. When people start eating vegan everythings all perfect. Time gives them a dose of reality. For some people it might be a few week whereas for another it might be a few months and for the extreme vegans it would be a few years(after all their bodily stores of nurtients are depleted).

Enjoy it while it lasts, or start eating a diet appropriate for the human species.

This is completely normal for people your healthier now and you get more stamina that you want to burn so your sex drive increases.

No, usually the exact opposite happens.
