Sexual Relationships 
Sexual Health 
When I was a personal trainer in college, I'd get a question people were totally unashamed to ask (which is great IMO). Other than cardio/weight management/healthy eating and the obvious general concepts, what are specific exercises to focus on improving sexual performance?
Here are 5 exercises applicable for both women and men.
1. Squats
Squats work your hamstrings (under thighs), quads (upper thighs), your back, your core and engage your entire body to lift the weight resting on your shoulders.
2. Planks
Planks are great to throw into your ab routine to keep things fresh and motivating. A front plank is literally holding the body position you see above. Focus on flexing your abs and keeping your core tight.
As you become more comfortable you can add more advanced variations like twisting your body side-to-side and lowering and raising your body towards the floor. Experienced lifters: definitely do this, and work on lifting your body up and down quickly and you'll feel it hits your Serratus as well, a very difficult little muscle group to hit.
This exercise is absolutely critical for men, since it simulates a thrusting position.
Just a warning, holding this position for a while (> 60 seconds) can quickly become absolutely brutal. You see rugby and American football teams throw this into team drills for a reason.
3. Decline board situps
Anyone in fitness that even casually reads sports science knows that your standard floor crunches/situps are not effective at engaging your entire core (although of course, better than nothing). Sitting on a decline board allows you to rip your core to shreds, which is what we want to accomplish!
Sit on a decline board and do whatever hurts the most. Sit ups, Russian twists, V-situps, whatever you want. The #1 rule is to fully stretch your core/rib cage at the bottom (eccentric) position of a situp, and fully contract and tighten your core at the top (concentric) position of the movement.
This exercise too, can easily become brutal. I would encourage someone to just focus on every rep and when it's too much, take a breather and do another set. Set, set, set, set focus on cranking out sets, as this will truly traumatize your muscles and allow for growth and development.
4. Mountain Climbers
Mountain climbers are performed by holding your body in a pushup position and alternating your knees in, close to your chest. Alternate, left knee, right knee. Go slow until you are comfortable with the motion and work on building your speed, while maintaining perfect form.
5. Leg Raises
Leg Raises can be performed in a couple different positions, seen above. on bench or hanging. I would discourage the "Captain's Chair" equipment where you hold your body up with your forearms, as this limits the stabilization your core can be exposed to, and limits the effectiveness.
Once in position, simply raise your legs, without moving them. Think of your legs are one object you are lifting with your abs only. The primary benefit of leg raises is how it targets your lower abs, it does this (arguably, of course) better than any other exercise.
Like all other exercises, focus on tightening the target muscle group. This is a critical peice that people forget, in all areas of lifting.
