A warm welcome to Susan's Vanessa...
Your son is young and probably will accept and not feel awkward about your changes.
For partners and loved ones, its a little harder, it tests, often core values that they may have had instilled in them since children and also often challenges their own sexuality. Many will support and bridge or get over the sexuality bit, some just can't.
Over time, especially if there is a bond beyond the sexual level, possibly will understand and accept and continue a strong relationship and fully support you.
Best wishes and good luck on your journey, however you decide to play it out.
Look forward to seeing you about the forum's
