Having been a single guy several times (twice divorced) and having learned from experience. I wouldn't date a woman who does NOT own at least one if she has been single for more than a few months. It has been my experience that a woman who enjoys sex and the big "O" will own at least one BOB (boyfriend on batteries). If she doesn't there is a good possibility she doesn't enjoy sex or doesn't not have pleasure as a priority. I will go out with a woman a while but when the relationship progresses to the point we are ready for intimacy it's one of my first questions. A couple times i had the conversation quite early in the dating process as i am quite sexual by nature. I don't understand the feelings of guilt, do you have guilty feelings enjoying a glass of wine, or buying yourself a new outfit? It might be a different story if you were using a toy as a substitute for the real thing in a committed relationship instead of seeking pleasure from your partner. My current partner owns several, had a couple when we met and we have since added to the 'toy box'. Sure we incorporate them in our relationship by mutual agreement and in ways we both enjoy but i honestly believe she doesn't use them to substitute for me, well except for the infrequent occasions i am out of town for the company.
My thoughts are: lose the guilty feelings, get a toy box started and admit you enjoy sex and the feelings and pleasure. It can be a great addition and add spice to a relationship.
