Lucca probably. Ayla definitely not. Marle prolly did it with Crono their wedding night. Frog maybe, but nothing conclusive either way. Magus got sodomized by Flea in the middle of the night, and is haunted to this day. Schala definitely was. Zeal, of course not. Fiona and Marco were like a couple of rabbits, unfortunately he was sterile due to a magic induced wound to the pills during the war, thus no descendants.
On to the Cross cast!
Leena, sadly for the rest of her life, you heard the fortune teller! Kid, probably, she does get rather embarrassed easily, and I can't imagine any lucky chaps getting past that temper into her pants. Serge, yes but only because he was stuck dating the romantically doomed Leena for all that time. Poshul, I don't even want to imagine. Radius, prolly not, I mean he did hang with the soldierin' crown all that time, I'm sure he took a shore leave or two. Karsh definitely is still futilely saving himself for Riddel, who incidentally already got with Dario before his passing in another. Guile's sexual escapades are *drumroll* an enigma... Surprised? Pierre still was at the start of the adventure (duh) but after becoming a true hero he was swimming in ladies until the end of time. Nikki and Miki may or may not have, hard to tell if any romantic waves are coming between them. ZOAH IS STILL A VIRGIN. Marcy is too, preserving any form of decency this thread has. Lynx certainly isn't (again, duh). Now Harle is questionable, I mean she is rather clingy to Monseur Lynx, but he seems more focused on being a douchebag to all the other characters and less interested in passing the evening hours with his painted dame.
This is a long list...
Wrapping up the rest of the Arni to Termina crowd, Glenn only found one use for his sword so far, Skelly never boned anyone, Greco has wrestled with a few in his day, Mojo doesn't work that way, Solt and Peppor have each other (take that however you will), Orcha has a finely tuned recipe for lovin', and of course, General Viper (thank God Riddel likely takes after her mom in the looks department.) Whew!
Now the Guldovian sexcapades! Macha's two kids are both inexperienced as can be, but are they adopted or something? They don't even look related. Steena is chaste (damn shame really). Orlha prolly has had a few drunken nights with handsome customers before. Finally, I don't know if I'm alone on this, but I'm pretty sure Doc has something goin' on with that nurse of his.
Moving on to the final virgin roster. Draggy yes, Fargo no, Funguy no, Grobyc-not-so-sure-what-he-did-pre-cyborg, Irenes no, Janice maybe, Leah yes, NeoFio yes, Norris yes (he's too stiff on his job, needs to lighten up etc.), Pip yes, Razzly yes, Sneff no, Sprigg no (she and Sneff maybe?
), Starky no (he tried a little something during one abduction.), Turnip yes, and Van of course yes.
There you have it.
