The generally unsettled feeling of something being not quite right won't necessarily go away just by sheer passage of time. Whether it does or not depends on a few factors, including in particular:
1) What precisely you're having the feeling about.
2) What conditioning is causing the dissonance, and how ingrained it is, or what values, and how integrated they are to the core of your person.
3) Your ability to reflect on the issue, comprehend it, and discern what will move you towards resolving it.
4) What actions you take to adapt, given the awareness from #3.
I'm putting this all in very neutral terms, because whether the feeling is a nuisance or an appropriate intuitive check depends on what precisely you're reacting to, and how it relates to your values.
Lastly, I'll elaborate on what I meant by #1. There are multiple aspects of the idea of hooking up from Grindr that could cause some internal resistance. It could be the homosexuality bit that is tripping you up. Alternatively, your issue could be with the casualness typically involved with hooking up off Grindr. Perhaps, more specifically, it's actually the thought of having sex with a stranger, whereas you wouldn't mind hooking up with a friend you knew. Maybe you fear for your physical health, and haven't yet figured out what you need to do to minimize that risk. Getting some sense of what it is that is causing you this internal unrest I think would be a solid starting point for figuring out how to proceed.
