You can absolutely have more sexual
partners. Human papiloma virus is
extremely common and in most cases not
terribly harmful - especially not harmful
to men. Some of the 100 different strains
have been implicated in cervical cancer,
and some of the strains cause genital
warts.
Here is some more information for you
about human papiloma virus from the
Centers for Disease Control and
Prevention:

According to the .C.D.C:
"At least 50 percent of sexually active
men and women acquire genital HPV
infection at some point in their lives. By
age 50, at least 80 percent of women will
have acquired genital HPV infection."
Also, condoms do not fully protect against
.H.P.V because there is usually still
skin-to-skin genital contact. It is
possible he got it from his coworker.
I read once on this forum that it can even
be spread by a handshake or a kiss, but I
haven't seen that from an accredited
source. I did read on an accredited
source that confirmed it could be spread
by methods other than intercourse but it
didn't get specific.
Don't worry about it too much. Read up on
it and learn as much as possible. This is
not a life-without-sex sentence.
