At any age, more so after 45 one can't just keep pumping hard , absolutely without any concern of getting Ejaculation. Once in a while I experience this and thrusting deep n hard looking into eyes ( which she find difficult when getting non stop pushes for minutes ) is amazing...in absolute control..not managing thrusting..but naturally it's not cumming n she is in awe ....once in 100 times this happens..how about you..no fear of Ejaculation despite non stop thrust only honest non medication cases to respond
