Try hookers, just be safe :D but seriously, I have the same issues. It took me two years to get used to the "worldy" (=normal) way of thinkig about relationships and sex. Now when I see a teen couple I no longer despise them.
I think your problem is more connected to your personality, maybe you are used to live and figure things out on your own. You need to socialize more; drinks do help to relax. Get out of your comfort zone.
