OK, your issues/questions in order.
1) Your suspicion of a chemical or physical irritation seems valid; your symptoms don’t sound like any STD. Such reactions typically are noticed within 1-2 days, too fast for most STDs. I wonder whether the lubricant also contained the spermicide nonoxynol-9, which can be particularly irritating. Using the product beyond the expiration date probably isn’t the issue. Having said all that, the one STD that conceivably could be going on is herpes, so be on the lookout for overt sores or blisters over the next few days. But if the symptoms continue unchanged or simply fade away, which I expect them to do, don’t lose sleep over it—but avoid the same kind of condom in the future.
2) In otherwise healthy persons, impotence—which happens from time to time in almost all men—doesn’t imply a serious health problem. Ecstacy, street drugs, and stimulants in general can affect erectile function, but not 3 years after last use; any effects will occur within days, or weeks at most.
3) Changes in stool appearance are mainly due to two things: diet; because what goes in obviously affects what comes out; and intestinal motility, because how fast things pass can affect completeness of digestion and water content. (One of your colon’s main jobs is to absorb water, “drying” intestinal contents to their normal consistency.) Coming back to what may be the central issue behind all 3 of your questions, one of the major things that affects intestinal motility is—you guessed it—anxiety and other mental stresses.
Bottom line: None of the problems you describes sounds like an STD or anything else that might be serious. Mellow out and perhaps it will all fade away.
Good luck-- HHH, MD

There was one more symptom related to my recent problem that I forgot to ask you about. For some reason now when I go to the bathroom my urination stream can't seem to shoot out straight like it used to. It sort of shoots every which way now. However, the redness has started to reduce around the tip of my penis and the pain when I urinate is getting less and less by the day but I am kind of curious as to why my urine isn't shooting as straight as it used to.
