I have a new BF and he's pretty good in bed, apart from one issue, which is a new one on me...
He doesn't seem to be able to cum from anything I do to him or with him. Not oral, penetration or me giving him a hand job.
He doesn't seem remotely bothered by this and, after a good old session together, he simply masturbates next to me to finish off. Takes but a few minutes.
Not quite sure what to do at that point though, other than lay next to him stroking his tummy. Seems odd not to be involved. :-/
