So I ask my girlfriend last night via text because I'm away with work for a couple months, how she would feel about me licking my own cum off of her. It's something that I haven't thought of before but last night it came to me as something that might turn her on. When I asked her she didn't seemed bothered by it at first but then she went very out of character very quickly and went to bed. I don't really know now if she would be okay with me trying it or not, or if now she is having doubts about my sexual orientation
I don’t think she’s having doubts about your sexual orentiation as the cum is yours - not someone else’s. She might not want to try it having thought about it though. That’s totally fine. Just ask her :)
Doing first conversations over text isn't a great idea really. Talk to her in person is nearly always the way to go!
Talking in person is better, it’s easier to get the reaction in real time and if you spring something like this up it may just be she’s not feeling it. If your away and she’s not having a genuinely good day then sex may be the last thing she wants to talk about. I would speak to her in person, but if she starts to build up walls then just leave it. Some people don’t really want to try certain things and if we love that person then you simply respect that and move on. Just remember that porn and fiction is two different worlds and this sort of thing can be seen as quite extreme.
Something like this needs to be brought up in a fun way but face to face conversation, Also in the text how did you bring it up, As you did it in text it might of not sounded that appealing, Something along the lines of I think it would be really Hot if I was to lick you out after I have cum in you so I would be taking in both of our Love Juices.
When I ask to do something for the first time I always like to try and make it sound fun and nice that is also involving my girlfriend.
EDIT: I didn't read your post right did I Ingram1 sorry, are you talking about cumming on her body and licking it off? Again this sort of thing is best asked face to face and in a fun way, but as you are away you can still bring it up in a saucy kinky email/text just to get her into thinking about it.
If you are still not sure what she thinks have you thought about making a masturbation video with you licking your cum off yourself.
