People are individual.
Some people simply know and are completely sure.
Others try some reversible steps first, or start hrt slowly to see how it makes them feel.
Some people say one in four hundred persons is transgender. So there are quite a few people, and there are some among them who would have done things differently. Don't forget that the vast majority is approving.
Further reasons might be too high expectations... dreams of how it would be nicer going back... and people saying so... I'd say simply listen to your inner voice then...
here are a few thoughts that could help:

and concerning dads, well it might be a possibliity to say that some girly stuff is not for you... you like more manly stuff... and do it together with him...
of course only if you like that and have a good feeling with it... well you know them best so its up to you what you say... and if it even makes sense .
Just take your time and think about it.
And you cou could have a look at this:
acceptingdad dot com/2013/08/05/to-the-unicorns-dad/
This is emotional stuff... if you feel like it call or chat on one of the helplines...
for example
glbthotline.org/hotline.html or
translifeline.org(Yet I don't like some of the comments, they talk about hurdles instead of the relief and that many people have made a successful transition and simply feel better. And many people say especially the younger generation is more accepting. )
Points imo could be:
would you like a bit more male body to be happy ?
And you do not have to feel male all the time.
How would you like to be perceived ?
