Hehbris, heres some tips on sucking your own dick.
Don't even bother trying in the morning. Most people are too stiff when they wake up. At end of day, your body's a lot looser.
A full stomach holds you back.
Stretching is a huge help. Here's a few starters:
legs together in front of you, seated on the floor. Lean forward, stretching your upper torso lengthwise across legs. Reach hands past feet to lengthen your back. Go back and forth between this position and the same stretch with soles of feet together/knees pointed out, rounding your back more than with straight leg version (tuck your head under. Do it naked! Look at that dick!)
Sit upright on floor with one heel at crotch and the other leg extended straight out as far to the side as you can bring it. Slowly bring your chest down over the extended leg. Take your time, this is a good one for loosening both your back and your hips.
Lie on stomach, hands at shoulders. Push up so your back arches backward. Hold, crane your neck upward, lengthen your spine.
Loosen your neck. It helps ease the stretch.
There are many more stretches, and taking a few yoga classes, you'll probably choose a few that really help.
Try different techniques. Head-over-heels is usually a good warmup. Try standing up and grabbing your thighs from behind. Pull outward with your back so your spine loosens and gets used to being rounded. Always focus on your dick. Move this grip up and down your thighs to the position that feels closest to your dickhead and remember (always) to TILT YOUR HIPS toward your face so that dick head gets closer. Don't expect to reach it the first time... or the tenth. But try this, then go back to head over heels and see if you're closer.
Use a mirror! Visualizing is half the battle. And if you prop a mirror on the back of your thighs while you're head-over-heels, seeing how close your hardon is to your mouth will help you get a lot closer -- the effect is wild. Don't get too crazy. Pop your load (it's hot seeing that, too) before you break your back.
Propping feet on the wall or something is good for head-over-heels, basically because it helps you to arch your back where it may not be used to arching. Push on the wall and you can bring your hips down closer to your face.
These are just a few tips. Don't rush things. Spend an hour stretching three nights a week for a week or two before you even give it a try. Obviously, a lot of exploring helps. You have to remember to use that idle time to your advantage! (Trust me, it's ****ing worth it).
