I'm Too Squeamy for Hot & Steamy

I've spoken about this before, but here I am at the sticky end of the situation (Err pun not intended)

The scene of this chapter has been unfolding, and I find myself coming to a screeching halt. A road block of sorts. As I'm writing the basic unfolding of emotions and sensations of what's happening in the start of this love/sex scene, I'm not sure if I should be avoiding the harder though realistic terms of whats happening or how to soften them (again no pun intended but apt)

I do know it's not me to do full explicit, but I also don't want it to be hidden behind dark curtains. I just don't know how to find the balance. What I have read so far have been on the extreme of either side. Does anyone know where is a good place to learn this balance?
