Do you go down on her? That might be a swaying factor. If you knock her socks off orally she may want to do the same for you because you make her feel amazing.
I honestly don't get girls like that. I love giving head, I think its so sexy and submissive when I'm on the floor looking up at him with his d*** in my mouth. I love it! lol you can do so much, fast and sloppy or slow and sensual and I'm very good at it. I like deep throating as well, and dirty talking a little, always giving him that sexy look or sometimes playing innocent. Boys are just so fun and I get really into pleasing my man. when I'm really into a guy, there's only a few things that I won't do. and if he's willing to try new things with me and make me happy, then it makes me wet just thinking about what I can do for him. I WANT to please him, to make him feel like he's king of the f***ing world. lol its true. I know some girls aren't into penises being in their mouths, they find it disgusting. my best friend is like that. I'm the opposite. I think some penises are so sexy, but even the ones that are just okay looking are hot because they are attached to the guy who I like and who I'm trying to please. then there's cum, which is awesome. come makes oral sex so hot. my guy has nice tasting come so I do swallow it for him when he wants me to, sometimes I just spit and let it dribble down my chin. I also let him put it wherever he wants - on my boobs, on my t*ts, and on face, etc. I love being his little cumwhore, and his alone. :)I'm just so into getting him off, its hard to understand where girls are coming from when they say they aren't into it. just look at the resopnse he gives you when your lips and tongue are on his d***...thats exactly what I love about it. he moans, he feels dominant, he feels good and he wants you even more.
i love oral sex. and no you should not feel guilty. every one has desires and yours are understandable. you should kindly explain to her how much you love going down on her (if you do) and just slide it in that wouldn't it be great if she got into that, into returning the favor, so that you could take your intimacy to a different place other than just regular sex. say how much you want it, but you don't want to pressure her and she doesn't have to do it if she doesn't want to, but you would be so happy if she thought about it. maybe suggest as a birthday gift or something? lol
if I were you I would just stop giving her oral if she's not going to reciprocate, but that's up to you. ladies need to take care of their men in bed. that's why half of them cheat and find girls who will do what you wont! just food for thought
