I've been dating with my girlfriend for about 5 months, I have to say I'm quite happy with her. We're both the same age (19).
Well, this weekend she was ill (stomach infection which got pretty bad) and because she lives alone in this city and has no family in town, I went to take care of her for the weekend.
I helped with home duties, cooker for her, washed her clothes and brought her food to bed so she wouldn't need to move out of her bed and rest.
This kinda got me thinking and I teased her with the idea that she was acting like a baby, and she followed my game playfully. So I asked her if she'd like me to spend the next weekend with her, at her place (it's something we do often). She said yes. Then I went on about treating her like a baby for a day (feeding her and what not), she just laughed at the idea, but though I was joking.
Then I mentioned diapers, and she didn't really like the idea. She said "Me? Diapers? That would be gross! Besides, do you even know how much do they cost? I don't like the idea of wetting a diaper. Also, who would change me?".
She accidentally came across some pictures I have in my laptop of girls in diapers, and she though it was funny, but didn't go beyond that. That's why I though it'd be possible to propose her that.
Anyway, I don't know if I should talk with her about this again or not, or to wait it out and try later on (in a few months, I guess).
Should I try again? And if so, how should I talk it out with her?
