check with your nutrition store...maybe it's you're low on B vitamins.and eat some meat.you might also want to choose a multiple vitamin.and get to your doctor and have a blood test to see what exactly you are lacking.

Stress, drugs, underwieght, or a chemical deficiency. I would recomend a simple blood test to tell you what is lacking.

see a doctor

I get tired after sex too, but not for that long. You need to see a doctor.

Well I would say coffee or something, or you know what about working out...get an energy drink to pump you up.

You feel so relaxed afterward that you feel as if you could sleep.

Try to do a small meditation before sex, and ask your body not to give up too much energy.
You could also ask the earth for the energy you need for the sex. For this you could sit with your back straight and put both hand with palms touching you body about 1 inch under your bellybutton. close you eyes and focus on your breathing for a while. Take long breaths, in a relaxing way, don't hyperventilate. then, try to imagine, as you inhale, that a flow of orange energy comes from the center of the earth towards the place where your hands are, where its been stored. As you exhale imagine that part of that energy expands within all of your body, revitalizing it. Do this for a while, asking the earth to give you as much energy as you are going to need. Before you are done, be sure to thank the earth for taking care of you.Also, you might try to check with your partner to see how he/she feels after sex. maybe he/she is taking some some energy out of you, without knowing it.Good luck, :)
