I don't recommend doing it. You wouldn't be satisfied (especially it would be you first time), and you would risk your health possibly for the rest of your life (condomns don't protect against every infection. I encourage you to educate yourself about these things beause people usually find out these things when it's too late). Try to satisfy yourself by other ways (e.g., masturbation), until someone comes along with whom you feel connected. Feeling desperate sexually is not a nice feeling (I think it's because you haven't had sex yet and probably watch a lot of porn and have some probably unrealstic expectations), but it also can push you to do damaging things to your self-respect and physical health. This is my advice to you. Be patient and hopefully things will turn around. Good luck
