I think you gotta reach over and grab her nose. Hold that sniffer shut tight. That's how people drink aspirin.
Eat some fruit bro, try to get it in your everyday diet. I tried eating fruit everyday and my ex loved the taste. Now I' am trying to find a way for my current gf to swallow, she barely likes giving head. Damn dude we are in the same boat.
ive been with girls that dont like sucking period...they sure wanted me to lick it though lol my fiance' loves giving me head. thank god! every time she swallows every last drop...she loves it.
Would say don't try to force her... but if she is willing to please you then Altman has some good advice. Eat pineapple to change the taste of your cum. Ask her if she likes it better and take some more baby steps. If you cum too much, maybe she can try a little first... Either way, make her feel like you're forcing her.
You're going to need to find something to do for her that she would really love and appreciate. A friend of mine once told me his wife used the BJ with swallow as a reward for him being especially attentive to her needs....sexually or otherwise. Like having dinner ready for her when she came back from a long day, or telling her to put her feet up and relax while he did the dishes. You can gently explain to her how much you would love it if she'd occasionally take you all the way and swallow and that you'd like to know what she would love for you to do for her on occasion....with no expectations on frequency. You'll likely need to let it happen. Relationships are all about giving and receiving. Good luck!
