The female bedbug has no sexual opening. To get around this, the male uses his penis
to DRILL A VAGINA into the female.
The process, known as "traumatic insemination" is a practice used by mites and
bedbugs, and a species of spider in Israel called "Harpactea sadistica".
In traumatic insemination the males pierce through the females' body wall to
inseminate directly into their body cavity. Their penises (or rather, the bug
equivalent) are sharp like hypodermic needles (they're pretty terrifying to look at
Female bedbugs have evolved with an abdominal region known as the "spermalege". The
spermalege is a body part that is specially designed to be easily pierceable to
minimize damage. Going through traumatic insemination reduces the overall lifespan of
a female bedbug, but if they go through the spermalege their bodies aren't damaged to
the point that it effects their ability to make more babies.
The Harpactea sadistica spiders, on the other hand, are much worse. The male spider
will pierce through the female's abdomen repeatedly, making two long rows of holes.
Sometimes several male spiders will join in. This method is clearly not very
effective and this species of spider is slowly shrinking into nonexistence.
