I have a problem with ruining sex.?

Maybe you're with the wrong guys?

Find someone you truly care for.

Luck

Well usually to have sex in the first place we are interested in doing it. You probably feel bored after 5 minutes. I used to be the same the sooner it would start I would want it finished. I felt like I had no pleasure in it what so ever and sometimes I still don't. I personally enjoy oral better than sex so I usually get my partner to give me oral until just before I go then we have sex and I find it VERY enjoyable because I am already reaaallly stimulated and mentally turned on.

Try thinking of something you really like and try that... If not be adventurous! ;)

That can be hard. I have had that issue myself. I did think for a while that I was either bi, or lesbian, but really I was just with the wrong guy. Now that I am with my fiance, it feels completely comfortable with doing things I never thought of doing before. Just relax, try new things if you want, if you feel better with men than women, or more with women than men, that is your choice you need to figure that out for yourself.

I think I need more info. Why are you stopping? It's boring? Does it hurt? You don't like it?

If you've tried a couple times with a couple people, it probably just means that you aren't attracted to them. Or perhaps to guys at all? I really don't know. Maybe talk to your ex. Ask him what he did, and ask your current guy to do the same. Does that work?

Maybe you need to find ways in making it more enjoyable for you. Try other positions. Tell your current boyfriend how you feel and that you want to try new things?

If your still trying to see if you are a lesbian and would like to find out just write me

Those guys dont turn you on. Something they do that bothers you. Could be a moan or a grunt. Or the way they say, come on baby.

Well what do you mean by "stop"? Do you push him off? Do you go completely still? Does it hurt? Feel uncomfortable? Is he too aggressive? Not enough?

ok here's the thing. just because men have stick and we got hole doesnt mean that every men and women fit.

you gots to find the man who got the tool that fits you internally and rubs your G spot with his penile head.

to do that you have to keep on searching for the man with right tool.

No more than likely you are simply a selfish lover. Sex should be like a chinese meal. It's not over until you both get your cookies.
