I have a new guy in my life and he is great! We seem to have a wonderful chemistry and sexual attraction however he has a hard time getting fully erect and staying that way long enough to cum.. he gets frustrated and I try not to make a big deal. He keeps trying but it never lasts till the end. He swears it’s not me but he also said it’s not typical for him .. what do I think or do? I am super afraid it is me and it will cause him to lose interest in pursuing something more.
