So why don't we have an option that is not a heart meant for love but fire meant for just pure lust.

Seems to me many of us would be willing to have a playthrough with that option tohave a playful relationship in bed like Izzy.
I mean I did pick the humor options when the heart wasn't present. We should be able to not use the heart and just humor and still bed him like Izzy. *sighs*
Apparently, it's true, slatterns do have more fun. <_<
:wizard:Perhaps a bed symbol as an attempt to bed that companion at that time.
Either it works or doesn't depending on the meter of how they will
respond. And that symbol is you initiating it.
Just for a physical only relationship doesn't guarantee loyalty.
But still keep the if you chose the love options and if the meter is just right then he will initiate it. As like when he was at your place and said to tell him to go if we wanted.
I would love a LUST option added to DA3!!! So much fun if that were to happen!
