Do you think it should be used for a man as well as a woman?
No, I don't think it should be. But who am I? It is not used that way anymore than a woman is called a stud, philanderer, or player.
Do you think this reasoning for why men are particular about the "kind" of woman they want to marry is acceptable?
MB, men are all different. Some are gentlemen and some are dogs. Women deserve respect.
Do you think this mindset of "a lot of men" is acceptable?
See above.
Maybe the meaning of the word should change or apply to both sexes. I'm curious to know what you think about that.
I am not in charge of whether the definitions of words should change or not. I don't know if slut should be made a neutral word and apply to both genders. Take a look at the first two definitions here:

SLUT - Definition
Now, take a look at the Wikipedia definition. It's all over the map and appears to have taken on a life of its own.
Slut - Wikipedia, the free encyclopedia
Slut is a
pejorative term for a person who is deemed sexually
promiscuous. The term has traditionally been applied to women and is generally used as an
insult or offensive term of disparagement.
Slut has also been
reclaimed as a
slang term in the
BDSM,
polyamorous and
gay and bisexual communities.
It may be used by the person concerned as an expression of
pride in their
status, or as an expression of
enviousness in the "success rate" of others.
The accepted denotative meaning is a sexually promiscuous woman or "a woman of a low or loose character; a bold or impudent girl; a hussy, jade."
The term
slut is therefore frequently used as an
insult. The
derogatory power of the term derives both from its denotative meaning of a promiscuous woman, but also from its historical and regional connotations or alternate meanings that identify a slut as a dirty or unkempt person.
It is often used against
gay males and bisexuals, comparing them without merit as people who are promiscuous in that they have, or are reputed to have, many sexual partners, or whose sexuality is voracious, indiscriminate, and shameful.
With
BDSM,
polyamorous and
non-monogamous people, in usage taken from the book
The Ethical Slut, the term has been
reclaimed as an expression of choice to openly have multiple
partners, and revel in that choice: "a slut is a person of any gender who has the courage to lead life according to the radical proposition that
sex is nice and pleasure is good for you."
The term is also used (principally by women) to describe a woman dressed provocatively or a woman being overtly flirtatious.
