Is it normal that i become rediculously aroused doing yoga stretches?

bit of a strange (and slightly gross one :P )but here goes, im a guy and ive got tight pelvic floor muscles, so i was recommended to do stretches many of which are used in yoga, they feel absolutely amazing and i get very sexually aroused, to the extent i can actually come a little in my boxers! IS THIS NORMAL?! my libido has become so high that once im done doing the 20 minutes of stretches i literally cannot resist taking my girl to the bedroom to let off some steam (which thankfully she absolutely adores), am i unlocking some type of khakra here? or is it something that should be of concern?
