Confession Time!

A few things I'm questioning/confessing here so please bear with me and sit back.

1. How do you know when you're in love? I know that you can physically show and feel when you're happy, sad, angry and jealous, but how do you know when you are in love? I've never been the 'head over heels' girl in a relationship and honestly I've only gone out with people who I would want a genuine life with, but I've never had the whole crush thing or being obsessed with my partner.

2. Is it normal to not like/want sex? I've been with my current partner for 8mths, he did take my virginity but I never really wanted sex often, he would ask almost weekly when we had the time and house to ourselves but I never really like it, I do say no at times, but sometimes i want to have sex. It still hurts/feels uncomfortable for me, I try to relax but I can't, I freeze up and I don't like it, but I want it at times. Ugh! It's so confusing! I also don't want to confront my partner at the moment as I want to think of a way of saying it without blaming him.

3. How do you know if your partner still likes you? I have bad habits that I've developed off my mum and seen what she's done to her partners, she's play wrestled, hit and insulted her partners and I've developed those. And I hate these habits, I sometimes wonder why he's still with me and I want to know how to stop it.

4. I've sent cheeky pictures to my partner and I've seen that he's screenshoted them to his phone, I want him to delete them but I don't know how to ask without being a cow about it.

In conclusion I'm an 18 year old who is still figuring out this game of love and I need the advice and guidance of others who have had similar experiences or know how to help or even just any piece of good advice. Thanks for reading my rant/confession, sorry if I wasted your time.
