I think it's best if you find someone who has the same goals as you do in life (no kids).....I like you didn't want kids but ended up getting married & the one time we didn't protect against getting pregnant was the time that I ended up pregnant......I wouldn't change having my daughter for anything.....but that was definitely NOT how I felt at the time because I feared it would have an impact on my other goals of degree & career.....it didn't....I had both....but I was definitely NOT good with kids....especially babies...I do ok with older kids but not young ones that you can't reason with.....just was NEVER something I was ever comfortable around & never had an interest to do babysitting while growing up either......so I understand that feeling.

Honestly you are better off if you have someone that is interested in having kids & you aren't to end the relationship.....I definitely tend to agree with Bill's analysis.....no sex....no possibility of having kids. After I had our daughter, I wouldn't go near my H until there was a permanent solution to never having more kids & my gynocologist wouldn't tie my tubes during the c-section because he said that he saw too many women who did that ended up having to have a hysterectomy & he highly recommended the solution be with the H....I figured that was fair in our situation.....gave him the option to leave if he didn't agree also but after freaking out about having to have a c-section (back in the late 70's)....I figured I did my part is having the one kid I determined was MY COMPROMISE.

There were so many other serious issues with our marriage that I really wish it had ended at that point rather than my continuing to tolerate it for 33 years. I found that when there is a difference in ideas on having kids...there are a LOT MORE differences that are hiding under the surface.

Casual sex you probably don't even know if the other guy is interested in kids so if you did get pregnant, you might not even take into consideration what the other person would feel about it....but when you become serious with someone then you probably would feel that they would have a say regarding the pregnancy so it's definitely easier to just abstain from sex than to have to deal with it......JUST A THOUGHT based on how my mind worked but in a different situation.
