Sex is separate from that feeling but sex can be used to intensify that feeling.
It is a power relationship between the protector (plumber) and the protected (you)
Being the protected appears to indicate you have less power but this is an illusion because you actually have more just as it appears the protector has more power (is able to protect) but actually has less. This is the paradox of power, the more you gain the less you have and the more you give away the more you aquire.
I have found the Tao of Power helpful in understanding this phenomenon.
The advantage of bending gender is discovering worlds outside the ones you know by the limits imposed on you through the roles previously assigned to you.
All relationships are power relationships. A kitten or puppy has power because it is cute so through attraction becomes valuable to those who are attracted. The cat and dog lose this power but gain others such as the ability to protect through aggressive defense.
What you experienced is not sexual but the awareness of another form of power that many woman take for granted because it usually is made available to them in differing degrees so it feels natural to experience it and they often rebel against it, intuitively understanding that it could entrap them
Power is that which can create/cause effect.
