Just tried this for the first time and it's pretty decent so far. Some odd moments that I had to end up rolling back on (Like the spa with Lana. Just thought it would of been nice to go, didn't know it was going to lead to sex) or some unavoidable things that I didn't want (Like feeling up Alex/Lily when applying sunscreen). I'm trying the Jenny path right now, so trying to stay faithful but the game kind of forces some things on you which I'm not very fond of. Overall though, not too bad excluding those little things that you can't avoid.
I did the get the bug as well at the boutique with Jenny and Alex where they say I asked them both, but I never asked Alex. I only asked Jenny, yet it still acts like I asked them both.
EDIT: Another bug, seems if you rejected Lana on her invite to the spa, it forces you to go to the spa anyways if you call Krista to hang out and have coffee. But if you don't call Krista and take a walk instead, you don't go to the spa. So looks like you can't have coffee with Krista without being forced to go to the spa with Lana (even though you said no to her about going).
