If you tighten your mucsle that happen. It happens to me when i do it for a long time.

How can i gain fat?

try to maintain your body relaxed and your penis stiff rather than holding adjectives of you too rigidly. That should ease the abdominal discomfort. Though as we adjectives know, when the orgasm hits you will have squally sensations and tightness all over especially if it's a really suitable one.
