I say this as a man.

I personally waited for my now wife, for about 2-3 months to have sex with her. She wasn't ready and I was respectful of her boundaries. It ended up as the most loving relationship I was ever a part of.

Keep in mind that if a woman wants to wait for sex, it can definitely be because she's worried you'd move on quickly after sex. So her wanting you to invest into her, is completely understandable.

If you as a woman are looking for a genuine relationship, make it clear to the guy that you like him (if you do), but you're simply restraining from sex because you want it to be a meaningful and serious relationship in the future.

Any guy I know that is genuinely a good person, and wants a stable, long term relationship, waited for his girl to be ready. If a man wants to, ladies, HE WILL TRY.

If he takes it as you not being interested in him, even though you're making it clear you are, it means he was just trying to get laid.

Don't go on wims and hope the guy won't next you after sex. Vet properly, and allow for good men to shine, while fuckboys run away.
