Its the hardest thing but all the more reason to wait for your soulmate and lead a happy life rather than fuck around and destroy yourself emotionally and physically.

There's no such thing as a "soulmate". There are thousands of people out there who're you compatible with. If you aren't really interested in sex, whatever, but people who engage in casual sex or sex with someone in a relationship that probably won't lead to marriage doesn't mean they're destroying themselves emotionally/physically.

I get attached to people fast so I'd rather get attached to someone who's made just for me and doesn't go around sleeping with other people

Even then there's no guarantee. Many people would want to have sex with someone BEFORE entering a relationship since they value sexual compatibility as important. And just because you're dating someone doesn't mean they won't leave you after having had sex with them.

It'd be fun to do things the first time together :)

It's certainly interesting, but it can also be very stressful and painful.
