Is it normal to have a lot of discharge with no strange color and a strong odor after being sexually active?
To have some discharge is ok, but to have a lot with a strong odor that is not ok. The only odor should be light, and just the smell of having sex. Not anything strong or foul. You should call your gyn as soon as possible to make an appt. If you don't have a gyn, ask a friend to recommend one or go to planned parenthood or a clinic like that. Good Luck!
I don't wholly agree with the previous answer.
You say you notice this 'after being sexually active.' How soon or long after sexual activity?
For example, if you have intercourse at night, might you notice it in the morning? Or if you have sex in the afternoon, do you notice it later that day?
If the answer is yes, the discharge may not be what is usually considered discharge. When you wash up or shower after sex, you may not be able to reach the most important spots. Often people just want to remove the obvious sticky traces that are external. But it doesn't take long after intercourse for semen to 'melt' (I don't know if there is a technical term for this) to a clear almost watery texture. Even very thick semen, seems to liquify and, along with a woman's own natural excretions, will run or drip out of her vagina. (You know what I mean... you stand up after sex and suddenly you feel it running down your thighs?)
But these sexual fluids, if the remain in the vagina for a while while develop an odor. And in my experience, it is semen that smells fishy, not a clean vagina.The discharge you speak of could very well be some remaining semen and vaginal excretions leaking out.
The only help for this would be to cleanse yourself more thoroughly after intercourse. A douche would work, but I don't like them because they wash away your natural lubrication (and I think they can upset your natural pH balance.) Using your own fingers or hands, or a *soft*, *clean* washcloth, you can often clean inside the vaginal canal a little ways, anyway. Be cautious of what kind of soap you use for this, too. It can cause irritation unless it's very mild.
Now, if what I've described doesn't fit your symptoms or situation, then I agree that you should consider discussing this with your doctor.
I had sex a month ago one time and just a few weeks later I noticed the odor it had no strange color or it didnt look different just the odor and alot for discharge.
While all the above answers are very good, did you use a condom? If not you may have contracted an STI such as chlamydia this infection can cause an increase in vaginal discharge with no odor while this is one of the symptoms many women have no sypmtoms so if this sounds like a possibility go to ob/gyn or your local clinic to get tested if it comes back positive don't worry you can cure this one , but b a little more cautious next time!!!!!!!!! Hope this helps a little. God Bless!
