A couple of random thoughts:
More penis options. Girth anyone? How about upwards curve, downward, sideways etc.
There should be another slider for romantic feelings ie love. Could be used to differentiate even more between physical attraction and deeper more mature love.
I wish there was options to actually talk with people. Learn where they live work and enjoy doing. What they enjoy sexually, what they have done sexually and what they would like to do etc. Who their friends are, if they can introduce you etc. something to start fleshing out the world.
Would be a great combination with a less complete sandbox gamemode like now and something more gamey. Slowly unluck sex acts, transitions between animations but most of all instead of freely switch around something where you have something like an in moment currency. Hornyness, initiative or something.
There is so much depth that could be had here. In my mind a lot of the fetishes and kinks don't revolve around the pure sex acts, it's about how you arrive at them. Is it a vanilla relationship, is it one where a gay character is helping a bi-curious to explore, is it a hotwife one with all the different variations of ntr? Or the submissive/dominant aspect of relationships submissive in bed doesn't necessary correlate to submissive in all aspects of life. I'd say that often the most dominant people have areas where they like being submissive.
And lastly some more randomness perhaps but one which mostly stays within the bound of the sliders so to say. If we get something that gamefys aspects more then having friends/lovers/partners have wants and needs that fluctuate would be interesting. They watched/read/spoke with someone that makes them want to try something new or you have been neglecting them etc etc.
Not as flashy as more scenes but what will keep LL moving forward is the development of core aspects I think!
