In general, I like a hairy chest.
If a guy is very hairy, then shaving in specific places looks weird (i.e.: hairy chest and stomach with shaved pubic and scrotal area); however please do trim these areas. Once I met a gent who was quite furry who shaved the area around his nipples because he liked them to be sucked and played with. With the contrast between his dark chest hair and two bald circles around his nipples, it took a lot of discipline not to laugh!
If you are not too hairy then a clean shave for the genitals and scrotum is wonderful!
If you have a uni-brow, then do pluck the middle so you will have two eyebrows. If you do not feel comfortable doing this yourself, you can have it done for about 15$.
Ear hair and nose hair are NEVER sexy.
