Yes. Is on my list. I've had many MFF. Always wanted to do a MMF but my ex got jealous when I brought it up & as a provider seeing two men at once can be scary!!
FMF/FFM/MFF or FFF yes lol....MMF/MFM **shrugs**. Mentally I don't think I like the dicks outnumbering the vaginas in the room live and in person (watching porn is another story).
