"You cannot blame porn. When I was young, I used to masturbate to Gilligan's Island."
Where to start?
So here's the deal, from a very young age we form ideas about porn and sex. This can vary based on when or how we were exposed to it. For example, the person who found their older siblings stash of porn or sex toy at an early age probably learned more at an earlier age. Usually, people who find out about sex and porn themselves are more open minded about the whole concept of it, because it is something that they discovered. Conversely, people who don't learn about what sex is until their Sex-Ed class in high school will generally have a more skewed opinion of it, because for starters, we all know what's taught in Sex-Ed classes isn't exactly honest. It's not limited to just this however. Someone raised in a highly conservative environment can also have very different views on porn.
Either way, regardless of where you started, if you want to genuinely enjoy porn there are plenty of ways to begin. The first step that I would recommend is to watch very different kinds of porn. Navigate to the "categories" section found on most porn sites and see if anything piques your interest. It's very important to not hold back because something is different.
Personally, I was raised in a strictly christian household. We lived in a small house and my mom would regularly have little "mini" talks with me about sex and the like. Usually, they'd just be stories about kids she grew up with that died jacking off or came blood. Keep in mind, this is when I was like 12 years old.
When I finally went to college, I started to watch porn more frequently. I knew I was an ass man (who can resist a sexy ass) and I was really aroused at the idea of anal (for a number of reasons), but I could never bring myself to click on the links. Eventually I took the dive, and I've loved it ever since.
Another good tip is to watch vague porn. This will expose you to many different kinds of kinks and fetishes very gradually, a good way to find out if you'll like something without too big a risk.
If you're totally lost, I highly suggest xArt. xArt is basically as real as porn gets: beautiful models, very sensual scenes, and it is also very enjoyable to watch with a partner. The best part about it is they usually have an "after-the-scene" scene, which usually involves the couple laying together or talking by each other. I know it sounds like I'm praising them a lot, but trust me, that's what they're known for.
Overall I think this is a great place for anyone to start, and this might be all you're looking for in porn, but I suggest that you do give yourself some time to check out different kinds. There's a reason there are so many types of porn out there. It doesn't really matter where or when you start, so long as you take it at a pace you are comfortable with. I believe anyone can enjoy porn, even as just a fantasy.
