She doesn't watch porn, actually.
>Do you kiss your gf after her giving you a blowjob?
Yes. I don't see why not. There is nothing gross on her lips, not kissing her would be weird and I want to kiss her.
>Do you give her cunnilingus after vaginal sex?
Not yet and I'd prefer not to if we use a condom or if I already came inside her. Condoms often make a pussy smell/taste weird and I don't want to eat/lick cum.
>Do you eat your cum after masturbating?
No.
>Would you autofellate yourself if you could?
I'd certainly try, but I don't think I'd do it regularly.
