Does having sex hurt or help a relationship? (In your opinion)

depends on the people.

sex within the relationship makes the relationship great. if the sex invovles cheating on one's significant other, it obviously hurts the relationship.

There is no undisputed answer on this. It all really goes down to what kind and how into the relationship it is.

Such would be that a person would have sex with another on a first date, and it doesn't last because there is little challenge in doing it. Having sex after say, a fourth date will make the sex seem more meaningful. And so, this in turn can filter out any people who just want sex as some one night stand, thus increasing the chance of being with someone willing to maintain a steady relationship.

But of course, there is the possiblity that it could be how the act itself was performed. Being really great at sex, foreplay and all, could bring about a more satisfying relationship. And being bad at sex(I don't know how you could possibly mess that up, unless you were a virgin) can in turn end a possible relationship.

Then again, it might not be sex itself that drastically affects a relationship, as there are other factors to consider like money and personality.

Not really, sex can be just as meaningful on the first date. If it feels like "it was meant to be" type thing.

There are a lot of things that affect a relationship. Personality, looks, positions of power, wealth, influence, fame, exclusivity etc.

But all in all i think that not having sex/being abstinent and if two people are willing to do that strengthens their relationship because they get closer so they can reach a goal. In other cases, having sex regularily keeps the relationship exciting. I do agree it depends on the relationship.

I would rather have sex ever day instead of wait a long time, so sex helps me personally.

FUCK man, you just reminded me of the time my exgirlfriend gave me the present of "not having sex for a month" because it would make it that much better. But it only went for 9 days.

Wasn't cool.

Haha that sure is funny.

I suppose it helps in small amounts but hurts in large amounts

sex in large amounts can NEVER be a bad thing.
unless you liek get an std
then its a fail
