Just enjoy her company, be friendly and faithful. Treat her with respect and as a partner in the relationship. Words won't do it. Don't just charm her and make promises you aren't willing to keep. Make sure that she knows you are happy being with her and that nothing else in the world would come close to making you as happy as she does. Make sure you are being a good boyfriend to and make sure that she knows you care and are trying.
You must show that you have a good safe word, like pumpernickel. Enjoy!
If your boyfriend doesn't like being in your company, showering you with love and respect, it is pointless to try and convince him other wise.
you shouldn't have to convince her, dont try to talk her into something that she's uncomfortable with. or if shes just scared get her relaxed and tell her it'll feel good and that you wont hurt her and dont!
Just be yourself.
Don't lie to her.
give her flowers
compliment her boobs
Tell her mom
tell her you will be safe and fine
you can't. maybe he is happy the way he is.
by letting her do her own thing
Tell him, "If I had feelings for him, I'd be his girlfriend.
