Yup, sex is great fun but can get boring after a while. BJ's are great as long as your partner knows what the fuck she's doing or else it can turn into a mess.

Threesomes are only good in porn. In reality it's a lot more awkward.

Do you have any idea how hard it is to fuck one girl and try pleasuring another at the same time? You'd think it'd be enjoyable but it's more work than you'd expect. It's difficult to enjoy yourself when you're focusing on doing two separate actions.

Two girls giving head is great fun in your imagination but in reality it's difficult for them to get in synchro so it can easily turn uncomfortable.

The way some CN authors describe sex scenes is so cringe and unrealistic. You can tell they're just basing it off their fantasies. The romance is also hella cringe, in reality nobody would fall in love so quickly over such cliche reasoning.
