Jean Guy is the first sativa strain I've ever tried and I must admit, I'm impressed! It is definitely an energizing weed and encourages complex thought. It's great for a creative night in or an intimate night with a partner. It does contribute to my libido, however not in the way indica strains do.
I really enjoy this strain, however I find that it's best smoked with someone else as it seems to encourage long, interesting conversations. In my experience, this is the kind of weed that makes you want to talk and cuddle for hours as opposed to making you super horny.
