help...

so I have always been into bdsm stuff. I found someone who would do it to me. I became his slave. he was my master. he wasn't a fan of being called daddy. well now that I have a boyfriend that I truly care about and never want to hurt him and if never ever sleep with my master again unless we break up. my master knows this and respects it but he's still always there for me. he's always there for me to vent to or if I'm super horny and craving being tied up I'll tell him. my boyfriend won't do that stuff though. his ex ruined it all and the most he's ever done was choke me. I really don't know what I'm doing wrong or how to get him to do stuff to really turn me on. my orgasms haven't been as good as when my master gave them to me. like I miss my master and being his slave....
