What do you mean? Tai's Route is linear. Excluding Kyrex's, it's impossible to miss any sex scene and there are no hidden ones either. Day 17 also contains two sex scenes, they were added in two seperate updates.

Hi Xevvy, what I meant is that there are 4 sex scene's in tai's route where you as the Husky rp with Tai twice. At the spa, you interact with Logan, and you make friends with him although you see he gets lonely at times because he has not many friends. This is where you sleep over at Logan's where his sex scene is introduced. This helps Logan feel confident in himself. Then the final sex scene is where the main character is at Tai's house for rp and Logan is introduced as well. This is where you unlock the last sex scene as a threesome.
