Too late. There a dev quote pretty much confirming romances (specifically alien romances) being included.
To be honest, I think the romances are worth it. I know it can be an issue on BSN, but I'd hate to see them remove them altogether. If they did a new IP, then I'd be cool with them not having them (although I'd be disappointed, to be honest). I'd rather not see them remove them from already existing IPs.
Good - It would not be a (modern) Bioware game without them (it's one of the features the company does best, so not including it would be bullshit...!)
So no, don't "set yourself free" devs - you aren't in prison (!) - just do it right this time.
No Bikini and underpants sex -.- (that's unrealistic and - pardon my french! - stupid!) scenes etc. (just ignore the damned media who think they can shame you for doing romantic content in an ADULT (!) game, while showing cruise missiles hitting buildings in foreign countries etc. - I mean chances are that those vocal and often female journalists enjoy reading corny romance novels at home (like 50 shades of grey -.- etc.) while trying to shame gamers for enjoying some similar content (only less descriptive, as we haven't had a game showing BDSM for example!) in their video games!))
