<human>: My boyfriend and I have been seeing each other for over a year now, we live together, get along great, wonderful sex life, but there's been a lingering issue...

He frequently masturbates, I've woken up in the middle of the night to him masturbating next to me, or that he's left the room and gone to jerk off somewhere, finding porn on his phone in the morning, just signs in general that he's been masturbating while I'm unaware/not awake/away.

Should this bother me? We've mildly discussed it and it's been an issue due to the fact that I feel incompetent as a partner to him, that I must not be sexually satisfying him if he needs to continually masturbate. 

We have a very healthy sex life, and for me this only contributes to the fact I feel his masturbation has a negative effect on my sexual confidence in the relationship.

I realize that this may be MY issue to over-come, I've told him that it's not something he needs to feel bad about, however I cannot shake this uncomfortable feeling I get upon discovering he's snuck away in the middle of the night to jerk of in comparison to waking me up to fool around instead.

What should I do? Is there something I can do to overcome this feeling so this is no longer an issue? I know he has his needs and urges that I can't understand, but is there something I can do to overcome this so our life is easier together in regard to this? Is there a way to compromise in this situation?

Can you give me the gist of the text in a nutshell?
<bot>: Boyfriend and myself have a healthy sexual relationship other than his need to masturbate which causes me to feel insecure. Halp?
