I like characters with whom I can relate. Well crafted prose always keeps me interested longer that the stark sex descriptions. Stories about things I have yet to try can be a huge turn-on!
Yes and yes - giving and receiving. Explosive, as many have already said.
I like women who are sexually confident. Surprise can be a turn-on, for sure. Taking the lead in various ways, being unpredictable, being spontaneous, introducing new ideas. Always exciting. I try to do the same for her.
Oh, yes. Bringing that level of intense pleasure for her is what I live for. The taste and smell, the sounds of her quickening breath and the primal, animal sounds she makes. The way she moves her hips as she starts to lose control. Exquisite.
