Optional content is always good! They are all nice but a little short and meaningless (yes I know thats the point) a little expansion could be good. Unless the feeling of 'ok we've had sex, beat it <Charname>' from most is intentional.
Yes and having a full romance that just involved someone special you always go back to would be nice, its already in as ribald but you'd have to rescue him or her in a complex quest in ToB, for example. Completly optional but if you refuse, your lover dies and your alignment can take a serios dip depending on how you justify it to yourself.
Like: "I never really loved him/her, she was just a great ****" - Selfish and Heartless. - Dip towards evil
"I couldn't risk myself in an obvious ambush, too many lives are at stake" - Neutral/Pragmatist, No alignment shift?
"It wasn't my fault he/she was killed" - Unwilling to accept that his/her connection with the innocent (or not so innocent) person was the reason they died. - Dip towards neutral
