Just remember that there is a lot of BS giving skinny guys false hope about expectations when it comes to weight lifting. YES you can make huge transformations from skinny to muscle naturally, but it does take time to make clean gains, and it takes a lot of effort.
Women can absolutely be a factor as to why you start training, but it should not be the only factor. This is just one part of making you a more complete man, if anything it will help you become more focused, more hardworking, you will notice yourself becoming more confident and driven -- it is all part of the package of self improvement and working on yourself for YOU. You gotta Patrick Bateman the **** out of it.
but i fell in love with lifting so i dont even care about what women think about it anymore to be honest
True for me also. Become who you want to be, not the guy that the girl you're currently interested in wants in a guy. Not all girls like a lot of muscle on guys, but also they have weird ideas about what 'too big' is or 'too muscly is', you just gotta leave it all in context and become the best person you can be, and people will notice.
Naturally getting girls will be part of that but to truly make good gains you will want to be in it for the full package.
You will be required to eat fairly strictly, getting your nutrition sorted as other posters have mentioned. Keep it simple when you start out, get a good program and eat a lot. When you're really skinny with a fast metabolism you have to be eating all the time. 5-6 meals a day type thing, with good sleep.
Keep in mind the other advantages of being a better built man. Each person has their 'thing'. If you're a weirdly skinny guy with not much dress sense, then people will look at you and probably not think much of you no matter what you are inside. If you pack on some mass, get your dress sorted, you can make an impression on
people. Forget specifically girls right now, because attention from people in general, or should I say respect - can help you immensely, even if that respect is built on nothing. It doesn't matter -- it's a way in the door. You can take it from there. If you're a well dress built guy who seems friendly or interesting, you demand some kind of attention that your otherwise way too skinny self might not get. And girls pick up on this. Guys pick up on this. People will want to be around you, your social status will increase. This is not to say you have to be built, but it is one way to get to this type of level.
Again though, this is not a get in the gym, do some bad form curls for 6 months and get ripped type of deal. You have to spend the time transforming your lifestyle to make it worthwhile, and it absolutely will be if you let it.
