It's possible, but it just requires a smidge of patience seeing as how my "Sheltered Catholic Boy" run went.
Basically rush to lower addiction by studying, then spam compliments every period as time allows (respectful ones obviously, except for Jean that is. Always go for "Nice Tits!" to remind her of her failure.) Dates were allowed so long as you go Dutch, with the gentlemanly walking them back to their rooms and immediately leaving once they're safely there. The odd sleep over was also allowed, so long as room was left for the Holy Spirit of course.
Was slow goings, but by day 40 all the ladies were throwing themselves at me in the shower and my days turned back into getting dragged back to my room, except now it was less for addiction fixes and more constant confessions of love and the like. Except for Jean of course, as somehow she considered me her 'Sexfriend' and I was about a day or two away from the threshold to get morning blowies.
Speaking of, Fun Fact: Telling a lady "Get my dick out of your mouth, please & thank you" incurs more of a stat hit than "No, I don't want to be your Boyfriend." Though I have a feeling no one really goes for that option to begin with.
