please ,please help me guys..........please

Hello every one, here is the story. I am ARIES and have been datting a LEO guy for the last three month. I like him a lot and he likes me as well(he drives for two hours to see me). The problem is that a week ago (after three weekks we had sex, i experianced some itching and redness........ I called him and asked him if I should worry about any thing and he saied ,no do not worry about any thing ,that he is clean....he was very nice about it,and said every thing is gooing to be ok. I went to the doctor the same day and found out it maight be from the detergent i have changed,so it tuned out to be nothing(i got screened for stds.)I caalled him and let him know that what the doctor said,and he was happy and wants to came to see me naxt week. The question is that I am very parranoid to have un protected sex any more. I trust him, but we have long distance relationship and we donot see each other on daily basis. After reading about stds and so on I do not think i want to take that kind of risk/chances.
What I am asking is that how do I tell him to use condos now after we have been talking about being deases free and so on. Will he think that I do not trust him?How do i tell him let starte using condoms now? please ,please help me.I LIKE HIM A LOT,AND DO NOT WANT TO LOOSE HIM,AND IN THE SAME TIME I DO NOT WANT TO GET ANY THING THAT I DO NOT WANT......PLEASE HELP ME IN HOW TO PRESENT MY FEER WITH OUT SOUNDING JEDJMENTAL AND NON -TRUSTING
THANKS GUYS

Asking him to use a condom is your natural right (even if it is your precuation). I think if he cannot digest that, he's not right person for you. Of course you need to speak with him about what happened and why you want to act like that in the future.

Thanks Haffo,for your response. What worries me is that since we have talked about every thing before we had unprotected sex, now for me to go back and say let us use condoms may make him think that I have something to hide? Especialy after the last epesode, do you think I actually found that something was going on and that is why i want the condom?please help i want to do this the right way..........thanks guys.
