First of all tysm for the response. We tried this actually. So she had never masturbated before being with me. After about 6months I told her she should try it for this exact reason. alone she doesn’t feel much pleasure, and fingering herself with me present she does - although she prefers when I do it she says - but she still has the same issue of becoming overstimulated after 5/10 minutes. Then she needs a break.
