Learn English – What’s the male version of “hottie”

I think the best you can do here is

A young couple emerged from the shadows.

If you need to specify gender, I would use young man or young woman as appropriate. While I agree with Charles that in spoken English young man is used more towards children, I would posit that this is the case only when addressing them directly. I could, for example, address a 15 year old boy as young man. It would make me sound professorial, but it would not be out of place.

However, if someone were to tell me they

saw a young man entering the house

I would think of a young adult, not a child.

Update:

The closest to guy would be youth but it only applies to males when used to refer to individuals as opposed to groups. Better, but also exclusively male, is lad but that is also more British than American. Kid can be used, but is ambiguous. An older person can refer to young adults as kids but it usually means children. Finally, and probably best in your case, you can use youngster(s). Once more, though, this is a term that is used by older people towards younger ones. It is more used for teenagers and young adults than for actual children but it also carries an implication that the person using the term is older than those she is describing.

The most common way to say "male chauvinist" is in fact male chauvinist.

But in your sentence, I would change it into an adjective:

Your ideology sounds a bit male chauvinistic to me.

Addendum (in response to comment)

It has been suggested in a comment that the word male could be omitted. Although the word chauvinist is (in my experience) most commonly heard in connection with male chauvinism, the meaning of the word is not actually restricted to that usage.

The following are definitions of chauvinism / chauvinist from three standard dictionaries:

chauvinism noun Chambers
derog an unreasonable belief, especially if aggressively expressed, in the superiority of one's own nation, sex, etc.
chauvinist noun, adj.
chauvinistic adj.
chauvinistically adverb
ETYMOLOGY: 19c: named after Nicolas Chauvin, a fanatically patriotic soldier under Napoleon.

chauvinist ODO
noun
a person displaying aggressive or exaggerated patriotism.
- a person displaying excessive or prejudiced support for their own cause, group, or sex:
- she wrote off all the local males as hopeless chauvinists
adjective
relating to or characteristic of a chauvinist:
- a chauvinist rejection of foreign interference

chauvinism M-W
1 : excessive or blind patriotism — compare jingoism
2 : undue partiality or attachment to a group or place to which one belongs or has belonged
3 : an attitude of superiority toward members of the opposite sex; also : behavior expressive of such an attitude
— chauvinist noun or adjective
— chauvinistic adjective
— chauvinistically adverb

It will be noted that the first definition in all three dictionaries relates to patriotism, rather than sexism. Indeed the word is derived from the name of a fanatically patriotic Napoleonic soldier.

Therefore, despite that fact that modern usage of the term seems primarily to relate to male sexism, it cannot always be assumed that that is the case. Indeed, there is nothing in the cited definitions to prevent the word being used to refer to female sexism. Having said that, if it is otherwise clear from the context that it is being used in reference, not only to sexism, but to male sexism, then, of course, the qualifier "male" could be omitted.
