Most Helpful Guy
It has made the dating scene a little harder, yes, it would be a lie to say otherwise. Anyone dating you has to consider that you have a child and that, if they were looking for something longer term, they would be taking on that responsibility. Guys of your age may not be ready for that responsibility. Guys in general may prefer to have a child of their own.
That said, there are plenty of guys out there who wouldn't be scared of taking on a child, particularly if they fell for you. Hope is far from lost. Guys take on this kind of scenario all the time.
What you need to do is to be sure about what you want and to make sure that you are cautious around new prospective guys. If you don't mind casual things and you aren't looking for a husband and a father then great. If you are looking for either of those things you need to try and be sure that new guys coming into your life are genuine and are genuinely interested in the longer term. Many guys might say all the right things if it gets them into your pants. It doesn't mean that they will be prepared to go the whole way.

I wouldn't be so quick to ask "Are guys mature enough to give me a chance?" because that sounds a bit condescending, as if a guy your age not wanting to father someone else's child indicates lack of maturity. It doesn't, if anything he's being more mature by admitting he can't handle the responsibility instead of hoping he can just get with you and ignore your kid.
Onto your actual question it will be more difficult in a sense but it's not impossible; there's always somebody out there who can appeal to your circumstance because they love you unconditionally.
