Telltale signs of the eternavirgin can include a deep interest in space opera or anime, attendance of sci-fi or fantasy-themed conventions, interest in cosplay, computer programming, mathematics, World of Warcraft, Dungeons and Dragons, Second Life, furry fandom, renfair, building model tanks or ships, etc. The eternavirgin often has poor hygiene and flatulence. Diet consists of ramen, jolt cola, and funyuns. Some eternavirgins however, are "nice guys" and may have a normal physical appearance, and may in fact have many female friends (all of whom have no interest in him sexually). Also, some are gay and can't come to terms with this fact. Note that not all of these conditions are mutually exclusive. For example, some eternavirgins are 1). geeky, 2). "nice guys", AND 3). self-hating, self-denying homosexuals. Aspies are also frequently eternavirgins. A few eternavirgins are genuinely asexual.
Note that the above information refers to the male variant of eternavirgin. Female eternavirgins CAN exhibit these traits, but much more often are just frigid and may be indistinguishable from normal (i.e., sex-having) females. Thus, female eternavirgins are much harder to spot. Discomfort when sex is being discussed may be a good way to ferret one out. Also, the subject owning more than two cats can be a sign. Like her male counterpart, the female eternavirgin may be homosexual and unable to accept this.
If an individual has hit age 30 and has never so much as gotten to first base, that person can consider himself a prime possibility for being an eternavirgin!
Nah bro, I had her last week. She's just an eternavirgin.
