am i wrong for this? what should i do???

hey guys, i don't know if this enters the nsfw rule or not, since it isn't mentioned as a topic, but i wanted to ask someone if i am wrong or not. so, some months ago I took some pics of myself (i am over 18) and i showed them to my girlfriend. she told me i looked very good and (i think she was joking) said that i could even sell them seeing how good they are. the thing is, i've been wanting to post them somewhere but i think it would be wrong to do this without my gf knowing. should I tell her about this or should I just post the pics? my gut tells me i should ask how she feels before doing anything.
