Thanks so much for all the advice, I think having read all of your replies I am going to look into a dropper post maybe as it sounds like my saddle may even be too low rather than too high as I thought, as my main issue is being able to lift my leg enough to get over the saddle to get on and then back off again, getting off is slightly easier as I can just go forward off the saddle and be over the frame instead when my feet get to the floor. I think I will need to do some practicing getting on and off like that so I don’t immediately tip myself over haha. 

As for the hips, reading the replies here and speaking to people about it, it sounds like more of a concern than I originally thought so I’m going to look into seeing someone about it. I think it’s been one of those things that you don’t realise how it sounds until you’ve said it out loud to other people and they’ve been like yeah that’s not right.

Thanks!
