Is pill required, what say

my boyfriend was quiet excited yday and thot to do doggy style with me, But I was nt comfortable doing that. So he just rubbed his dikk coveerd with cndm , on my back upper thighs. The only problem is that unfortunately the cdm was bad as I did feel a lil wet at that place. Pls. tell me that it might be because of his sprms Or it could be just water , came out of rubbin lubricated condm. It ws hardly A Minute whne he did rub on upper thighs. because firstly I was nt comfortable and secondly, I was reporting it being wet.

Now what I want to know is that do you think I should take some ipill types…my boyfriend says thr isn’t anything to worry and no pill needed because he thinks it cant enter my vgina this way, as I was with panty but he did remove it later after removing his dikk . He did not enter direct not even in my asss, but I am worrying because I heard that if there is any sprms , they themselves travel so fast and hit your spot, Can I get pregnt. this way…Pls share…
