You have every right to end a relationship if you aren’t getting your needs met, intimacy is very important in a relationship for those who need it.

However, what right do you have to cheat and hurt another person by betraying trust? I can’t even stress how damaging cheating can be to the person on the other side of things, not just the hurt of finding out about betrayal but this could potentially have life long damaging implications for her. Trusting another person is really really difficult to do far after a relationship ends, self doubt, self unworthy... the list goes on.

Think about it. Far better to end it due to lack of sex and thinking you’re an arse for it, than betraying her and her thinking for years to follow that there’s something wrong with her.
