I had a lesbian cousin. She was not religious before she realized that homosexuality was wrong. She became a Catholic and is now a celibate nun. Homosexuality can be cured. God can help. Do I love my cousin? Do I disapporve of her behavior when she was less mature? Absolutely.
If by "cured" you mean "becoming a celibate nun", yeah.. it can be cured. Does she still fantasize about women? Probably.
