The question would catch me off guard a bit, but I am open to a lot of "in the moment action". Usually a girl will explain a little before about what she likes and where her boundaries are. Sex can be a primal and passionate experience and communicating boundaries is important.
Strive toward your own definition of success, the challenges that come during that journey are merely opportunities to prove yourself.
I did when I was younger with girlfriends. Now it's just foreplay while we drive home from a date or event. The excitement of trying not to get caught heightens the experience.
I love performing oral sex on a woman. The feel of the soft skin around her inner thighs, a swollen slippery vagina, and a hard clitorus invoke primal urges that set the "mood" for the rest of the night.
Ladies first. I try to make my spouse intoxicated with sexual pleasure and multiple orgasms. My experience is inhanced by her passion and intensity.
If she is sexually confident and uses her breast during sex as a form of expression that is a good thing and I feel that size is a non issue for me.
I try and run about 4 to 5 times a week outdoors. I do not enjoy a treadmill or a machine rather a nice natural view and the changing leaves. Hockey is also good at getting my heart rate up and football once or twice a year usually on Thankgiving although the older I get football seems more like abuse than excercise.
Answer is yes. I do almost anything that the female finds enjoyable when it comes to the exchange of body fluids. That time during the experience is very pleasurable and intimate.
In my experience, the female has to be at a certain level of arousal for this to occur. As a guy, its interesting to me to try and achieve this level with my spouse on every occasion and I think my spouse views this reaction as a form of her feminine sexual expression.
