Sex is good. It's erotic, passionate, loving, rough, brutal, exciting, sensual, moving, terrifying, wonderful, tender, soft, forceful, submissive, liberating, kinky, perverted, dirty, cleansing and, above all, sexy.
People (me included) have too many hangups and fears about sex and so they make porn and they make it dirty because they think sex is dirty, they look at it in secret and feel ashamed.
Sex is not shameful. Your pussy is beautiful and tight and it smells and tastes wonderful. Your dick is big and hard and she (he?) loves the way it feels deep inside. Stop letting the internet, your parents, all those ignorant highschool dipshits or anybody else make you think any differently.
