My boyfriend is affectionate but isn't interested in sex much anymore, I need help!
My boyfriend is 28 and I'm 24. We have been together 9 months now, living together about 2 months. I just want to give some background information into our relationship: He was married at 23 and divorced by 25, and he's had a string of short relationships before he met me. He is very affectionate and playful, says he loves me very much, and the thought of spending the rest of his life with me doesn't scare him.
Last month we had a pregnancy scare, he was excited about having a baby, and when I found out I wasn't pregnant he told me when I'm ready and settled in my new job we'd have a baby. We are very sexually open and have 3somes from time to time. He has women as friends, and jokes around with them via Whatsapp and msn, he doesn't hide any of this from me and he knows I trust him enough not to cause an issue with it, and he is very respectful and does make a change if I have a problem with anything.
He works very hard, leaves home at 5:30am and gets back at 7 most days. When we first started dating the sex was very passionate and regular, but recently (even before I moved in with him) we have been having sex maybe once a week, sometimes twice, only on weekends. I've tried talking to him about it, and he said that I can't be happy, I get what I want and then I always want more, and that he's tired from work etc so we're having sex as much as is practical.
I've tried sending him a naughty message on his phone complete with pictures, got no response from him, and when I asked him if he got the message he said "yes, but I deleted the pics because they were dark." When we do have sex it seems like I always have to initiate it. I don't know what to do anymore. I'm not sure if he is just focusing on other things, and this is just a phase he's going through, I hope that's the issue and it's not that he's cheating. He's the type of person that needs to get one thing done before he moves on to another, and he's a bit obsessive about it, so maybe he's focusing on his career right now and isn't thinking about sex, but it's bothering me, and talking to him about it makes him feel like I can never be satisfied with anything he does for me, and that I'm always asking for more and more.
I feel like I'm only asking for what I deserve, as in having an intimate relationship with my boyfriend, connecting with him on another level, closer than we are with anyone else, but I don't know how to talk to him without sounding like a nag and someone who takes everything else he does for me for granted.
Please help me, I know it's a long post, but I really need some kind of comfort or advice. Thank you.
