I can't engage in the one thing that gives meaning to my life.

If there's anything I've learned from life it's that the things we crave the most are the least likely to make us happy. Consider that the amount of time you would actually spend enjoying yourself would probably only be minutes at best, and while we often think that our obsessive horny thoughts are pleasant, they're actually a pretty horrible kind of suffering.

Wouldn't the greatest form of happiness come from having no feelings of compulsion, desire, or need? Are you being driven towards your desires with whips and thirst, or do you float towards them effortlessly enjoying the whole pathway there? If you're anything like me, it's probably the first one. Especially when it comes to sexual desires. Sexuality isn't a source of contentment, so it's wrong to say it will make you happy. You may find relief from your cravings at the end of a sexual encounter, but that isn't happiness, it's just the absence of desire. You can diffuse your desires other way and find real happiness in their absense.

To put it simply - you're wrong to say there is some thing that makes everyone happy. Happiness has nothing to do with things, it's just the absence of suffering we're all looking for. We can find this in brief moments by letting ourselves get carried away on our cravings and breifly satisfying them, but this is sort lived and fragile - especially in your case where your desires are likely to get you in lots of trouble. It's much simpler just to give up on cravings and compulsions and let go of them. Then you can be happy without doing anything at all.
