If you're catching yourself weirded out by being attracted to tomboys, your brain has been corrupted by modern progressivism and gender theory shit.
You assume that a tomboy is less of a woman/girl than a "feminine, real" woman, which is lunacy and departs from the biological essence of sex.
Tomboys are NOT manly women, btw. Tomboys are generally the "pixie" stereotype, typically able to mingle with boys and have fun with them. You might encounter them in your basketball or volleyball teams at the school. In the past when we played outside, you could find tomboys more interested in doing what the boys did, instead of the "girly" stuff that females usually started to get into at 13-14 - fashion, boy bands, self-care. Instead, a tomboy might be just found with her brother and his friends exploring the nearby wood or some old ruins of a deserted factory.
Tomboy women and girls are exactly as feminine and good mates as any other more stereotypical women. If you think that shorter hair, propensity to like more stereotypically male stuff and being thin is gonna affect a personal relationship, you're wrong. It will be the exact same thing,
