Is it worth staying together?

Phoenix

So me and my boyfriend when we met all we did was hookup we both each other's bootycall. After like a month we decided we wanted more from each other and we started going out and we started dating he's met all of my family and we've spent a lot of time with them he gets along with them great and they love him. We live an hour apart though and I'm the only one with a job and license so we only get to see each other when I'm not working or busy. We've been kinda struggling with that because we both want to be there all the time and neither of us has had to go a week or so at a time without seeing the person were dating. I'm not used to it and especially since I have a high sex drive it's hard for me because I'm horny all the time. Lately I've tried sexting and talking dirty to him and phone sex and he's not interested in any of it he always just says he's not horny. When we do see each other we do have sex quite a bit, but it's always doggy style or something like that not at all intimate. We decided on an open relationship thinking maybe that'd make things easier, but the thought of him sleeping with someone else with how we are now is unbearable. We're trying to fix things problem by problem and it's been going good so far, but anytime I talk about our sex life he just apologizes and I feel horrible about bringing it up. Also on an unrelated note is it nor.al that just about everytime I gave sex it hurts like I used to think it was just cause i. really tight, but I just found out that's not normal. And it's not a problem with getting wet because I am soaked like 24/7. Thanks(:
