Boyfriends Penis Goes Down When Changing Positions..

Likely nothing to do with you. try to change positions quickly. for ti to go down I have to think that there is a lot of standing around during those position changes. Your boyfriend should also stroke his shaft to keep up the momentum when he pulls out.

Your boyfriend just needs to learn to be more attentive to how his body works and you'll be fine. Part of it involves just knowing how to maintain the erection, both mentally and physically (by stroking for example).

The biggest issue is usually mental. He's probably either stressed out or is focusing too hard on something. Many times the thing he's focusing on too much is making you feel good which, in turn, makes him forget that he needs to do the same for himself. He just needs to learn to relax during sex. (I've had this problem for years, and it's still a problem. It usually takes me a few days when I'm with a new partner before I can actually maintain an erection.)

Oh, and feel free to help him by using your hands. Having someone else touch your erogenous zones is always quite stimulating and is a pretty quick way of getting a guy excited again. :-)

It's definitely not you though, so just do your best to be patient with him when it happens. If he sees it upsetting you it will likely just upset him, which will make it worse. Just work with him, don't rush and, most importantly, enjoy each other's bodies other ways while you're waiting for it come back up. You might even find out some new things that you both enjoy during those in-between periods. :-)

Another columnist has explained this by saying that your boyfriend has to use his higher brain functions to change positions, and that distracts from the lusty, lower brain function that keep the penis firm.

That may be true, but it may also just be a fancy way of saying that the break in action has refocused his attention.

As they've suggested above, try a little manual stimulation to keep his interest "up"! XD
