Sorry for bumping this, but I have to thank the posters of this thread.
It made me curious so I looked, and yup, definitely attracted to guys and not just the penis itself.
A milestone for sure, and while it doesn't answer everything it certainly makes a big difference and a big leap towards self-acceptance.
It comes down now to gay or bi, but straight is 100% definitely off the table.
A big thanks to the undoubtedly nsfw (but not pornographic) thread titled "PYF D**ks" thread on the SA forums.
I would recommend anyone confused similar to the OP to try looking at non pornographic pictures of guys.
You'll know pretty quick if it's the male body turning you on, or just his penis.
