Tamaki does like it tho, he just feels guilty that he does because of mommy issues, so in the end its not 'rapey' its just guilty pleasure. That is also what makes shun such a chad, by doing what he did, the 'guilt' that Tamaki feels when he has sexual feelings just goes to Shun, leaving it to a win-win.

Yikes, I would much rather have them break their dating for a year deal than this, it makes me kinda sad that Shun just doesn't get the memo and keeps pushing. The sex scene felt kinda rapey to me. Maybe they could have kept that scene but with different timing and Shun actually listening to Tamaki.
I really feel like Tamaki is asexual and just hasn't realized yet. It would be very nice if Shun could just stop trying to push his idea of a sexual relationship with Tamaki and maybe just being in a romantic relationship without the sex bit instead? I don't know if Tamaki is also aromantic, but I think it could be a different route to take, and it'd be cute and refreshing for once
