female genitalia are mostly internal. The external labium (lips) of the
vulva occupies approximately the same physical location on the body as
the scrotum would on a male. In the wintertime, when the female enters
estrus, the vulva becomes hot and puffy (hence the term "in heat"). This
puffy/swelling makes the female visually interesting to males, and
along with the pheromones produced in the vagina, indicates when the
bitch is physically ready to mate. The puffy vulva is also ideally
shaped so that the tip of the male's penis can easily hook into its fold
to be directed into the vagina during copulation. During copulation the
male thrusts his penis into and out of the female's vagina while
shifting his weight from one leg to the other in order to work his
bulbus glandis into her. This locks the male's penis into the female's
cervix, which undulates to stimulate his penis to erection. Erection
expands the bulbus glandis and ties the two Wolves together; thus coitus
is
achieved. Once coitus is achieved, the female's vaginal sphincter
muscles tighten around the male's bulbus glandis to hold it firm as she
pulls forward, triggering ejaculation of semen into the uterus. In the
initial 30-50 seconds of the tie, the male deposits only clear semen
until orgasm is achieved. During the initial 30 seconds or so of orgasm,
a cloudy, somewhat thicker, sperm bearing semen is ejaculated; thus
insemination is achieved. After insemination the semen returns to a
clear state, but continues to pump forth until the end of the tie, which
may last up to 35 minutes. |
