<human>: Condense the text into a few key points

Good morning. Basically I've [29 M] been dating this girl [29 F] for about 3 months now and we get along really well. We're on the same page about everything, always laughing, really enjoy each others company, share similar hobbies. Some other background that might be relevent. In the past she has only dating older, more established men. I've started my own business and things are stressful at times, but I work my schedule around to see her. I also make a decent living but she makes significantly more than me. Though she isn't a materialistic driven person.

The problem has been about sex. I can get my gf to orgasm pretty easily (both oral and normal sex) but I haven't been able to orgasm myself when I'm with her. Sex is pleasurable for me, I love feeling her body and we've had some hot moments. In the beginning she said it doesn't bother her much but last night she told me It really does bothers her. She doesn't feel fulfilled that she can't get me off and she feels awkward after I get her off because she doesn't know what to do. It has gotten to the point that she didn't want to see me on the weekend because she didn't want that feeling of awkwardness after sex. I didn't post this in /r/sex because I know my problem is that I have death grip which basically is that I masterbate too rough and I need a lot of stimulus to get me to orgasm. I've tried not to masterbate for a few days so I can be more sensitive but it doesn't work. Sometimes I wonder if I have a pencil dick but I'm about 5" in circumference and I can feel her. Even lately I have become more comfortable/intimate with her and I'll masterbate with her after sex so I can get off, but it seems like it is not enough. I'm not sure if she is using this to avoid a bigger problem in the relationship (which I can't imagine what it is because everything she's to be going well). I really like this girl, I haven't felt this way about someone for a long time. Anyway I'm not sure what I can do.
<bot>: been with this girl, everything is going great except sex. I get her off, I can't, she feels unfulfilled. Not sure what to do.
