The acknowledgement of how pathetic and shameful peeping is... haha. That's good.
Also, wow, a Basic Instinct reference.
Wait... they're acknowledging a preference for big tits. I suppose it's like rumors about women liking big dick. I mean, there might be a number that do, especially the shallower-minded ones, but so long as it's a decent fit, I'm pretty sure that's all that matters. To be honest, I think my ex said I was either just a bit too big, or almost too big, for her. She was fairly short, especially next to me, so she was probably smaller in general in that respect compared to most. I'm not very big, but she still called me 'above average' (far as I'm aware, this is true).
The condom thing is kinda odd, but I guess it makes sense. There's probably no real-world counterpart, unless you want to talk about the awkward idea of women putting them on with their mouths. I seem to recall a manga or whatever I read having a character that had never tried it before attempt it, fumble, then the guy just said 'screw it' and simply ignored the condom.
Anyway, yeah, TroubleFait has a point about possible rights imbalances... not to mention you'll probably be looked down on for being a manwhore if word gets around. Might even have women thinking you're a bit too loose, ya' know? Just like in this world, we've got people judging women for sleeping around. MC (and the comic itself) even comments on this at points.
Good luck settling down, if you ever get the inclination. The number of people I've seen shit-talk whore characters in stories and whether they can even reform for the right partner...

So... the dark haired one, Keiko it seems? She kinda gives me a bit of a Jane from Daria vibe. Light haired one, Suzuka, doesn't really feel like Daria herself, other than the glasses and the fact her hair on the cover is a brown shade kinda like Daria... but, in general, she hits a lot of my preferences. To be honest, you get a meganekko with long, non-blonde hair (a nice chest doesn't hurt), and I'm usually interested. I'd rather get another short girl like my ex, though, too. She was a shortstack, and the same for my last crush after her, too.
On a long-term narrative note... I feel like Kawashima is getting possessive of him. Not that a gag strip like this has any real solid narrative. Though, still, she's on the majority of the cover images for the chapters.
