You worry about an act that would damn your soul if fornicatiously done (videlicet, outside of marital union), yet take no concern about your eternal salvation. You are like a fool, whose ship is sinking, and rather than jump off to a life boat, you encumber it all the more, adding more and more weight. Each sin you do, and each sinful thought thought, and each sin even desired only multiplies the weight of this burden. Accept Christ, earnestly and sincerely repent and confess your sins before it's too late. You may have even less than "might hit earth next year". You could die tomorrow, and if you die in a state of mortal sin, you will go to hell for all eternity.
