The 4th finger to index finger digit ratio is merely an indicator of prenatal testosterone exposure and has nothing to do with your current testosterone levels. 
The studies shows that if you're a guy, and your index finger is longer than your ring finger, you're most likely GHEY.
		
		
	 
most likely perhaps. But certainly not definitely.
 
When i look at a picture of a young naked woman, i feel my body getting aroused and my mind fills up with mental images with her enjoying me while doing the horizontal salsa(If i let it get that far, that is...). Of course if she has that special feminine magic.
For example : Strangely enough although i do not desire her, i still find Serene Williams very feminine besides her muscled build. 
Unfortunately deceased, but still a prime example of beauty according to myself :
		
		
	
	
I do not get turned on at all on by women of the "butch" type in build and behavior. 
Also feminine males in behavior or build such as the singer of Tokio hotel make me feel awkward.
When i look at a picture of a young naked man, i feel a strong sensation 
of disgust and the typical male (all reptile brain) characteristic to see if i am physically dominant in a fight. 
Consciously, i feel anger rise and muscle tension increase as does my breathing alter. 
Feel free to test it out if any of you experience the same. 
Now i am curious.
P.S. The picture is of a dutch actress.
