It’s like my 20th time having sex and it’s finally starting to feel good.Watch
'Normal' is a tricky one with sex - ideally sex should always be enjoyable and not painful. However, it's normal for it to take awhile for you and your partner(s) to be comfortable with each other, be relaxed, and know each others' bodies well. If you can, speak to your partner(s) about what you do and don't enjoy, what you'd like them to do, and check in with them too (maybe they also didn't find the first 19 times so great!) Hopefully, the sex will just keep getting better.
Is this with the same partner ? If so, 20 times is a lot to start enjoying sex. If you had a lot of sex in a short time, like a few weeks that might explain it as you are more relaxed now. Besides, sex is like the weather, sometimes its nice or even great - other times not so good. Thats normal.
