AS a cis female, heterosexual, trying to transition to FTM, look at it this way. If the guys are hitting on you, you've arrived!!!
it is one of the difficult things about being female, stick around, and I'm sure you will get to experience all the other "great " things about being a female. Oh Wait, you won't ever have to worry about a period.
Sorry for the flip presentation. You will get used to guys being jerks around you, it is just a part of female life.
