Look, you know what you need to do and it is going to happen eventually anyway.

Yes, you "love" him. But you aren't going to spend your entire life with him and you know that. Your relationship is already a patchwork of compromises and some of those are compromises neither of you should be having to make for a long term relationship.

You don't know if you are lesbian yet because you have yet to have sex with anyone that you really connect with sexually. It might need a woman, but you might feel that connection with a different man. You wont know until you find out.

The love you have for him is not good enough to put aside a lifetime of sexual connection and satisfaction for yourself, and neither is the love he has for you. You realise that you cannot satisfy him as a sexual partner either? Yes, you can have sex with him and make him orgasm. But he has much better sexual experiences ahead of him with someone else who actually wants to sleep with him.

You can't sustain a relationship where you feel disgusted in any way by your partner. You must know this.

Free both of you rather than delaying the inevitable
