I think part of the problem is how shy many /. readers are. Leave the house, go somewhere where you can meet girls, that would appreciate your qualities(I don't know try a book club). I think a lot of the problem is people pick who ever show any interest in them. Rather than going out and showing interest in others, but if you go out and show interest in others you will be surprised how many women were waiting for you to do that(stay in your league, make sure they are the type of girl that appreciates what you have to offer).
Once you do that then....
You need to decide what you want out of life and what's most important to you, and what doesn't matter so much.
I would never watch a romantic comedy on my own, but if my girlfriend has one she wants to watch, we watch it. Then sometimes we watch action movies.
"no major compromises" is a term a friend once said to me, and I think that's really the way to do thing. No one will ever be exactly perfect, but don't settle for someone who won't match with you on the REALLY important things.
I've had several people tell me I shouldn't worry about similar political views, only for me to find out later that they care which college football team their wife cheers for(I of course want a girl who doesn't care about football games).
Now back to porn.
Some people think it's inappropriate to emphasize sexual related things, personally I think that's stupid. Sex plays an important role in relationships and you need to on the same level. It is perfectly valid to end a relationship based off of different sexual view points.
There are people who believe that sex should only be used for procreation. There are married people who are ok with each other having sex with other people(sometimes in the same room, sometimes not). There are people who believe you should live together and have sex for several years before getting married and there are people who believe you should wait until you are married to have sex.
You need to decide what you want, and if you want to watch porn with your girlfriend, then bring it up at and appropriate point and move on if she disagrees. It's really not that hard to find a girl that would go for it(I live in one of the most conservative parts of the country, you can't legally rent porn here, but I know women that enjoy watching porn).
Decide what's most important to you and keep looking. It was tempting at times for me to settle for less than I wanted. I'm a bit of a social out cast so I got really lonely at times, but it was worth the wait.
