I had my lobes pierced when I was about 8, which would have been right in the panicky-try-to-be-really-girly phase. They were done with a gun and not by an experienced piercer so not only was I allergic to the metal they used, but I also got a bad infection and had to take them out. Tried a second time a couple years later, with the same result. I opted to leave the earrings out and let the holes close. They did, to some extent, in that after a short while I couldn't put anything through them anymore but about 9 years later the hole marks are still there. All this to say, friends I've known for several years reacted with surprise when I mentioned the old hole marks on my lobes; they hadn't even noticed.
About three months ago I got a double helix in my right ear, which is something I'd wanted to do for awhile. Since it's a non-standard piercing, it doesn't have as concrete of a gender to most people, but honestly I don't think piercings are really gendered at all, even the basic lobes. Most people determine gender by the jewelry put in the piercings and not by the piercings themselves. Wearing simple studs or rings in lobe piercings would be perfectly normal for a guy. If you decide you want to keep them then that'd be a good choice if you wanted to go for a strictly masculine appearance. Obviously if you don't care as much and it doesn't affect passing for you you can go crazy and do whatever you want! 😀 Otherwise, you can let the holes close and most people will probably never even register it.
