It's important to open yourself up to love and affection. Try to let go of anxiety and love yourself as you love your boyfriend. If you have issues with anxiety and self-esteem, it's important to work on those issues separately from your relationship with your boyfriend.  If you struggle with anxiety issues, or struggle in other ways, talk to someone about it. Seek out a doctor, or a close friend to talk about your anxiety. You can be open and honest with your boyfriend, but don't burden him with your issues if it hurts your relationship.  Look your best so you feel confident and loving with your boyfriend. You don't have to look any particular way to love your boyfriend, but if it would make you feel more confident and loving with your boyfriend, make some little changes. Get in shape or dress up if it will help. Before you're physically intimate with your boyfriend, make sure that you want to and that you're old enough and responsible enough to show your love physically. Always practice safe sex and communicate with your boyfriend before you do. If your boyfriend will only be with you if you have sex before you're ready, or send him pictures on your phone that you don't want to send, break up with him. He's manipulating you and is being unfair. Love yourself enough to stand up for yourself and move at your own speed. Lots of people think that the guy will always initiate the kissing and the physical love part of a relationship. This doesn't have to be the case. If you want to show your boyfriend that you love him, don't wait around for him to make a move. If you're feeling love, make a move yourself every now and then. This will help him to feel loved, and will help you to feel closer to him. Even if you've been together a while, try to remember what it was like when you first got together and rekindle some of that attitude when you're together. Tell him that he turns you on. Tell him what you want to do together.  Leave him little notes throughout the day if you want to turn your boyfriend on. Delay the gratification, so you'll keep the sexual tension up all day until you get back to your place.  Tease him physically as well. Give him a little kiss on the side of the neck when you're out in public together and whisper in his ear. Drive him wild. Your love life can get stale pretty quickly if you don't put some work into it. If you want to love your boyfriend, find little ways to keep your life in and out of the bedroom fresh and exciting for you.  Try having sex at different times and in different places than normal. If you want to do it, don't always do it in the same place. Try out new moves. Experiment with some kink. Dress up and role-play. Talk about what you like, and find out what he likes. All guys are different. It's always better to find out from your boyfriend what feels good and what turns him on, instead of reading some list on the Internet or from a magazine.

Summary:
Love yourself. Move at your own pace. Initiate sometimes. Flirt and tease your boyfriend. Spice it up.
