hmmhm good question,, just for brevity, i'm gonna interpret this question as asking to what extent i would draw my sona having rough sex, alright ? ok so like

technically i DON"T KNOW right now- i haven't drawn a line yet, so there's a gray area. i know for a fact i wouldn't draw my sona getting violently beaten/bruised or in excessive pain, BUT ON THE OTHER HAND, i'm COMPLETELY OKAY with her getting noncon'd !! uhhhh i still feel like this is still really abstract and hard to explain so imma just rapid-fire a few things i know i'm okay with

i think my sona crying during sex is hot. my sona having sex with someone who's larger than her is awesome (especially if their cock is a little too large for her, but maybe not TOO big). being roughly handled like a sex toy is cool (though i think it'd be difficult! she's small but not THAT small so realistically you'd have to hold her with both hands if you're trying to use her like a fleshlight). grabbing and pulling her tail is awesome. hair pulling is a maybe because i don't find it that hot. grabbing roughly and groping is hot. my sona being bitten is really hot (i get a ticklish/tingly feeling all over my body if i get bitten so she'd experience this too). noncon including forced oral is hot (including gagging and choking on cum is fine),,,,,,, uhhhhhh sex toys and anal plugs/beads are fine, anal sex is a maybe because i'm not disgusted by it but i prefer vaginal (i probably wouldn't draw her having ROUGH anal sex) and uh .. ,.., ., .,.,.,........... yeah idk there's just so many different things

if you have a specific thing you wanna know if i'm okay with, you can just ask ! i doubt i'd be offended or disgusted by anything you'd come up with . at the end of the day my sona is a fictional character so like whatever
