Absolutely! You will have some opportunities in various activities you could do with Ophelia. For example, you can go on a picnic with her and give her compliment about her figure or discuss sex stuff will increase her lust. Then if her love and lust are high enough, a sex scene will trigger during that picnic. Note that some dialogue choice will be hidden by default until you get enough love. Such activities will be repeatable so it will be possible to unlock all possible scene for a specific event.
Other characters will also have something similar.
