Hi  V. Manohar,

from my own experience with glaucoma, caused by an injury to my eye,
yes sex will increase the pressure in the eye. As will almost anything
that puts a strain on the body, any kind of effort has the same result
of increasing pressure, eg lifting a heavy object, overeating, etc. But
the effects are only temporary, and go when the strain being exerted
goes. Hope that helps,

Robyn
