So I've been RPing with another girl for about a year and a half. At first our RP was never intended to be sexual, but slowly our characters started to become more drawn to each other and finally she proposed that we let them be a couple. I agreed eagerly because secretly had hoped for the same. Eventually our characters started to do sexual things and finally we both went all out and let them have full-on graphic sex. At first it was exciting and stimulating. Just reading her replies got me wet. But now it's not the same. It's really lost the spark. We've done who knows how many sex scenes now and they just don't do it for me anymore, and it's depressing because that's one of the things I loved about our RP. Everything else in the RP is going okay, but the sex is just... dull. It's basically become the same sequence of events over and over again. Is there any way I can spice things up and keep it sexy?
