Guess what. You can be straight and be HIV positive too.
The average life span among homosexual men is about 20 years shorter then heterosexual men. This is because homosexual men are prone to other diseases including “Gay-Bowel Syndrome.”
The military's not worried about exploding blood flying across the battlefield. They test often for HIV, and have a very good handle on who has what. Anyone deploying that pops positive for HIV during their SRP (medical testing) isn't going into combat. That testing is what reduces the risk, not whether or not gay troops are open or hidden. That whole line of reasoning shows a dim understanding of HIV is transmitted and how the military operates.
(A far, far greater medial concern is contact with bleeding foreign nationals than bleeding American troops.)
If the generals cared about this, you'd hear it. They care about unit cohesion, enlistment/reenlistment rates, and turning the Army into a pro-gay megaphone.
Not very likely, unless you're a junkie.

“Straight” men who are HIV positive are 99% IV drug users, the other 1% are lying.
It is VERY difficult for a man to contract HIV from heterosexual sex.
