Do you think my girlfriend will send me nudes of her if I ask?
Uh, I couldn't say. What do you think?
Well, she hasn't shown me any, yet.
While many couples enjoy sending explicit photos to each other, there are also couples that do not find that practice appropriate. Before requesting your girlfriend send you nude photos, you should talk with her to see if she thinks that is something acceptable to do or not. You should always respect your partner's wishes and not ask for or send explicit photos when they aren't wanted.
I'm going to do it.
You really should talk with her first to see if this is something she is comfortable with. Your relationship will be stronger if she trusts you.
