I am 32 yr old married women.Last week i went for office trip along with my colleague(another married women) to other city.We went to hotel after our work.At night time while watching TV she touched me. I liked so i didn't stopped her. Finally she undressed me and we ended up having sex.I had my Orgasm with her.I had never thought of this before.Even it was her who initiated.I know its my mistake that i let her do it. I love my hubby and my kid too much.But now I am confused. Because she want me to continue this on occasional basis. She told me its just for change and no harm.( Does this make me a lesbian?)
