Eliz, why gross? Women masturbate too. Be it with tools or their fingers. If you want to prepare yourself, then you gotta train your body to be ready. Those muscles needs to be explored to discover for yourself how you like to be touched.
If you find fingering gross, u will probably find sex gross. Most guys be it straight or gay do have some level of sexual fetish. We love blow jobs and panting. Can be anything from uniforms, MasterSlave, anal or cum swap.
