Really good watch, would watch again, and can recommend.
It has a fairly unique and wonderful concept. Being able to step away from sex as a part of life, as he's not part of it, he's basically got a super power, be it a gift or a curse.
Launching into him going through puberty late in life is funny enough all on it's own. Throwing in a "in love with the girl next door" trope, and a "my 2 idiot friends", the movie is charged with comedic potential.
The cast is all fantastic, and nail their roles. As long as you're okay with sex as a subject, then you're likely going to find this movie enjoyable.
