There is nothing wrong with what you are feeling or saying. I do wonder what kind of background you have though, and why you feel the need to be nurtured by them. It does seem like you want approval more than anything else - maybe even more than a sexual relationship with these older women.
Since you said you aren't really sexual towards them, I can't help but think you want someone to love you for who you are and that older women might be more accepting of this than younger.
Just don't let them take advantage of your vulnerability. Some people act like they care so they can get something from you. Make it clear you just want compatibility, not anything more.
