>I've done pretty much everything she could potentially ask for to re-ignite things - lost 10lbs, more romantic gestures, spending plenty of time together - but to no avail.

You've done well thus far. Now you need to start friendly flirting with other women and evaluating them as partners. Don't cheat for the next few months but if she still doesn't respond then move on.

Your balls don't hit her clit hard enough
when you're pounding it. That's why she doesn't
want you to stick her.

be more sexual aggressive

Healthy couples don't spend all their time together. Go out and do something else, without her. Be okay with yourself, alone. Do this and your relationship might heal with time.

The alternative is that you break up with her. That's okay too. You don't have to hate someone to realize that you aren't compatible.
