If, being Catholic, you wish to follow the precepts of the Catholic Church, no.
According to the Catechism of the Catholic Church, all of the baptized are called to chastity. Offenses against chastity include lust, masturbation, fornication, pornography, prostitution, and rape. The offense here is fornication, defined as “carnal union between an unmarried man and an unmarried woman.” It is a sin of grave matter, which qualifies it for mortal sin. Mortal sin causes you to fall from a state of grace, severing your relationship with God.
Sorry pal.
